Private Residence

Wakacyjna 2, Koszelówka — a whole house for twenty-four, on four fenced hectares by the lake.

Salon z kominkiem w Argentum Private Residence
The house

Six bedrooms. Six bathrooms. Nobody waits.

Six bedrooms, each with a double bed and a sofa bed for two — four people per bedroom, twenty-four guests in the whole house. Six bathrooms. A large living room with a fireplace, a fully equipped kitchen and a games room with a pool table.

  • A dining table for 24 in the house — and a second one in the covered barbecue house outside.
  • Fireplace in the living room — the heart of autumn and winter here.
  • Bed linen, towels and bathrobes are included in the price.
  • Fast Wi‑Fi across the estate, strong enough to work from.
  • Pets welcome at no extra charge — bowls and a bed are waiting for them.
  • Smoking is allowed outside, on the terrace and in the barbecue house.
  • Invoices issued — ready for company bookings.
Spa & wellness

Warm all year. Especially when it isn't.

Infrared sauna, steam cabin and a six-person jacuzzi — all inside, all yours, no time slots. The heated outdoor pool runs from 1 April until 2 November; the rest of the year belongs to the fireplace, the sauna and the ice-cold Lake Zdworskie — the largest lake in the Gostynin Lake District — three hundred metres away.

The pool is heated by vacuum solar panels, so the water follows the weather — distinctly warm after sunny days, cooler after a few cloudy ones. If you would rather not leave it to chance, we bring it up to a comfortable temperature for your whole stay — PLN 1,000 per weekend.

The grounds

Four hectares. Fenced. Yours.

A private forest thick with mushrooms in September, a stocked pond you can fish, a private beach and Lake Zdworskie, the largest in the Gostynin Lake District, three hundred metres from the door. A nature reserve begins where the fence ends.

  • Covered barbecue and a fire pit.
  • Electric bikes, cycling routes and hiking trails from the gate.
  • A dog can run off the lead — the whole estate is fenced.
  • Kayaks, pedal boats and SUP boards in summer — ice dipping in the lake in winter.

Included in every stay

Four cocktails. Unlimited. The whole stay.

Four cocktails made on premium Polish vodka, poured without limit for the whole stay and included in the price of the house. Not billed by the glass, not added at checkout, not an upsell. Almost nobody rents a house this way — and that is exactly why we do.

  • Pornstar Martini · Sex on the Beach · Blue Lagoon · Pink Ladyall made on premium Polish vodka, refilled through the whole stay
  • No counting glasses, no bar tab, no surprise at checkout.
  • Wine and the host’s liqueurs on request.
Bar Argentum Resort — drinki bez limitu
Kitchen and table

One table. Twenty-four places.

One dinner, one table, all twenty-four of you at once — no splitting into two sittings and no hunting for a restaurant that will take twenty-four people at nine in the evening. A second table of the same size stands in the covered barbecue house. The kitchen is yours for the whole stay, and if you would rather not cook, we cook for you.

  • Twenty-four places at one tablein the same room as the kitchen, the bar and the fireplace — and a second table in the covered barbecue house
  • A fully equipped kitchen, yours around the clock for the whole stay.
  • Our own kitchen and cooks — breakfasts, dinners and buffets priced individually, for your group and your dates.
  • Catering is not included in the price of the house. We say so up front, before you ask.

How booking works
  1. 01

    You choose the dates

    Pick your dates in the calendar and send the enquiry. We reply within 24 hours with confirmation of availability and the full quote.

  2. 02

    We hold the dates — 48 h

    Once you accept the quote we put the dates on hold for 48 hours and send you the rental agreement together with the transfer details. The deposit is 50% of the price, payable within 3 days of signing. In the calendar the dates turn on hold.

  3. 03

    Confirmed booking

    When the deposit lands we send a written confirmation and the dates become booked in the calendar. The balance and the refundable damage deposit of 3 000 zł are paid before arrival.

The calendar shows availability only — never the names or details of other guests. Dates blocked on Booking.com and in our own channels appear here automatically.

The agreement

Every stay is confirmed by a short-term rental agreement. Here is what matters most in it — you can read the whole template before you decide.

Payments

A deposit of 50% of the price, payable within 3 days of signing, holds the dates. If it does not arrive in time, the agreement simply ends. The balance is due before arrival — full payment is the condition for handing over the house.

Damage deposit

A refundable damage deposit of 3 000 zł, paid before arrival. If nothing is damaged we return it in full within 5 days of departure. Normal wear and tear is on us, not on you.

Number of guests

The price covers a stay for up to 24 people. A larger group needs to be agreed with us in advance — the house is rented whole, to one group at a time.

Pets

Welcome, free of charge — a bowl and a bed are waiting. The agreement asks only that you keep an eye on them: you cover damage and any cleaning beyond the usual.

Spa area

Yours for the whole stay, all year. Two rules: no glass right by the jacuzzi, and under-18s use the spa with an adult. Nobody touches the technical settings.

Changes and cancellation

Extending the stay and any cancellation are agreed in writing — an e-mail, a text or a WhatsApp message is enough. Cancellation terms follow art. 394 of the Polish Civil Code and are set out in §5 and §8.

Template agreement (PDF)

The full document you will sign, with the amounts and dates left blank. Bank details are not in it — we send them with the booking confirmation, never publish them on a website.

“An outstanding stay, a wonderful location, a clean pool, a brand-new spa zone, nature to rest in, a big estate to walk around, electric bikes and a delicious breakfast.”

Marcin · Polska · 10/10

“A great spot for a weekend or a longer stay. A very large, comfortable house, fully equipped, with a separate spa zone. Electric bikes, a big garden, fast internet if you need to work. Service and hospitality at the highest level.”

Rafał · Polska · 10/10

“The pool, the sauna and the jacuzzi are in perfect condition — you can see everything is looked after with great care. We had complete privacy. We warmly recommend this place to anyone who wants to rest in nature near Warsaw without giving up a high standard.”

Oleksandra · Ukraina · 10/10

“Beautifully situated in the middle of the forest. The quiet and the privacy are wonderful. The house is furnished superbly and has a cosy spa area. The lovely garden with the pool and the lake leaves nothing to be desired. The host is very friendly and helpful. We would absolutely recommend this place.”

Questions

What guests ask before booking

How do I book, and how does payment work?
Pick the first and last night in the calendar in the ‘Pick your dates’ section and send the enquiry — the dates go into the form on their own. We reply within 24 hours with confirmation of availability and the full quote. When you accept it we hold the dates for 48 hours and send you the short-term rental agreement together with the transfer details. The deposit is 50% of the price, payable within 3 days of signing; if it does not arrive in time the agreement simply ends. Once the deposit lands the booking is confirmed. The balance and a refundable damage deposit of 3 000 zł are paid before arrival — we settle the damage deposit within 5 days of departure. You can download the template agreement in the ‘The agreement’ section; the bank details go out with the booking confirmation, never on this page.
How many people does the house sleep?
Argentum Private Residence sleeps up to 24 guests. There are 6 bedrooms — each with a double bed and a sofa bed for two, so four people per bedroom — and 6 bathrooms. The dining table seats 24, and there is a second table for 24 in the covered barbecue house outside.
Can I book a single room?
No. The house is rented whole, to one group at a time. You never share the spa, the pool, the kitchen or the grounds with strangers. The price is for the house, not per person.
How much does one night cost?
It depends on the season and the day. In the winter season: 2 500 zł per night Monday to Thursday and 3 250 zł per night at the weekend. In the pool season (1 April until 2 November): 2 750 zł and 3 750 zł. The price is for the whole estate, whether you come as two or as twenty-four, with a minimum stay of two nights. With a full house of 24 that works out at 135 zł per person per night in winter and 156 zł in the pool season. Holidays and special dates have their own rates — St Andrew’s night 7 500 zł for two nights, Christmas 19 500 zł for four, winter school holidays 20 000 zł for a week.
Can we hold a hen party, a stag weekend or a party here?
Yes — and we recommend it. The whole estate is yours, the nearest neighbours are far away, and the house was set up for exactly this: an open bar, a spa with no time limits, a pool table, darts, a games room, shisha, a covered barbecue and a fire pit.
Are the drinks really included?
Yes. Four cocktails made on premium Polish vodka — Pornstar Martini, Sex on the Beach, Blue Lagoon and Pink Lady — poured without limit and refilled through the whole stay, at no extra charge. Wine and the host’s liqueurs are available on request. Nothing is counted by the glass and nothing is added at checkout.
Is the pool open in winter?
No. The heated outdoor pool runs from 1 April until 2 November, and it is not covered, so it also depends on the weather. Through the winter the house works differently: the fireplace, the infrared sauna, the steam cabin, the jacuzzi and ice dipping in Lake Zdworskie three hundred metres away.
What is in the spa?
An infrared sauna, a steam cabin and a jacuzzi for six, plus a relaxation area with loungers and a pool table nearby. It is inside the house, open all year, with no time slots and no booking — it belongs to your group for the whole stay.
Can we bring a dog?
Yes, at no extra charge. Bowls and a dog bed are waiting on site. The whole four-hectare estate is fenced, so a dog can run off the lead.
Is there catering?
Yes. We have our own kitchen and our own chefs, so meals are prepared in-house without a middleman — breakfasts, dinners, a Christmas Eve supper or a New Year’s Eve menu. Meals are not included in the price of the estate: breakfasts and full board are quoted individually, for your group and your dates. Tell us what you need in the enquiry form and we will price it.
How far is it from Warsaw?
About 90 minutes by car from Warsaw and 15 km from Płock. The address is Wakacyjna 2, 09-520 Koszelówka, by Lake Zdworskie. Warsaw Modlin airport is 76 km away and an airport transfer can be arranged. Parking on site is free and private.
Do you issue invoices for companies?
Yes. We issue VAT invoices, which makes the house straightforward to book for team offsites, planning workshops and company Christmas parties.
How warm is the pool?
The pool is heated by vacuum solar panels, so the water temperature follows the sunshine — distinctly warm after sunny days, cooler after a few cloudy ones. On request we heat it to a comfortable temperature for your whole stay: PLN 1,000 per weekend. It is best arranged when you book, so we can have it ready before you arrive.
When can we check in and when do we have to leave?
Check-in is between 3 pm and 6 pm, check-out between 8 am and 11 am. If you need different hours, mention it when you book — we arrange those individually.
