9 months for students. 3 months for guests.
Capital working 12 months a year.
It is an investment product, not a flat. You buy a separate unit that will get its own land and mortgage register (KW), the operator runs the lets for a fixed commission of 15% of revenue, and you receive the statement. The model is designed for Olsztyn: 25,000 UWM students during the academic year and Old Town guests from July to September.

This is an estimate, not a guarantee: rates and occupancy depend on the market, the season and the unit’s standard. We don’t guarantee the rate of return. We show our assumptions so you can check them and calculate it your own way. Play with the numbers and see for yourself that it works.
*90% as a safety factor for possible vacancies.
Without the operator, you pay no commission, but you take on the letting management — guests, cleaning, laundry, booking platforms — yourself.
1.07 · 19,24 m² · 1 room: 2570 zł × 9 mo. × 0,9 + 435 zł × 90 days × 0,5 = 20 817 + 19 575 = 40 392 zł gross per year. Operator fee 15% → 34 333 zł for you. Investment: price 310 000 zł + fit-out 67 340 zł = 377 340 zł → Net ROI 9,1%. For comparison: with the operator 9,1%, without the operator 10,7%.

Booking platforms, finding and vetting tenants, photos, cleaning, bed linen and statements. One fixed rate for every unit. What exactly does the operator do →
You can let it out yourself, on your own terms — in that case, all the revenue and all the management are down to you. The operator model is an offer, not an obligation.
You live there all year round, for part of the year, or you hand the unit to the operator just for the season. The unit is yours — the building’s ecosystem is available whenever you want it.
These are revenue estimates, not a guarantee: rates and occupancy depend on the market, the season and the unit’s standard. Monthly rent and the price per night rise with the number of rooms and the floor area, and units with a special feature — a private terrace, a mezzanine, a second-floor view of the park — have rates with a premium. For every unit we give them in the table below and on its unit card. You can change every figure in the calculator.
A hotel in summer. A premium student residence in term time.
No reception desk — the building runs itself.
We are creating a product for a specific group of customers. The common areas work in both scenarios: the restaurant on the ground floor, the laundry and the sauna with a plunge tub in the basement, a playroom or study area on the first floor, the lift, parking at the door. Access to the building, the apartment and the services — via the app, at any time.

Breakfast for guests, lunch and dinner for Old Town residents. During the academic year — a lunch subscription for tenants. Use it or not — your choice.
- Local produce, a seasonal menu
- Dining room, full kitchen and back of house on the ground floor
- The unit builds the reputation of the address

Hotel bed linen and towels washed on site — a faster turnaround between guests. For tenants, a self-service laundry of a standard no student hall can match.
- Premium washers and dryers
- Detergent included
- Booking and payment in the app
A six-person sauna and a cold-water plunge tub beneath the basement’s vaulted ceiling. After a day in Mazury for guests, after an exhausting day for tenants — an argument no other apartment in the Old Town can offer.
- A sauna for 6 and a cold-water plunge tub
- Booking hours in the app
- Upkeep in the operator’s hands
One room with windows along the whole wall. In the holidays a playroom for children, in the academic year a reading room and study room.
- Nine metres of glazing, facing south
- Families stay longer, students have somewhere to study
- Upkeep is the operator’s responsibility, within the commission




A lift, two stairwells, corridors that keep the character of the old building.
- Wide doors, quiet and fast
- New and safe
- LED lighting, CCTV

19 parking spaces on the plot (7 required by the local plan + 12 extra) and a large public car park right in front of the entrance.
- Entry from ul. Okopowa
- Spaces for guests and tenants
- An EV charger can be fitted

The whole building runs on smart access. Guests and tenants open the door with their phone, the owner sees everything in the panel.
- Entry to the building and the apartment: code, QR, NFC
- Self check-in at any hour
- Online service booking and payments
- Owner panel: income, bookings, reports

ROI table — the same rules for every unit.
Net price from the price list, turnkey finish, monthly rent and price per night per the operator’s assumptions for the given floor area and number of rooms (units with a special feature, marked ✦, have rates with a premium), operator commission 15%. The last column shows the ROI if you let it yourself — commission-free. Click a unit to change the assumptions in its calculation.

All figures: September 2026, net prices, excluding VAT (refundable). Estimates per the operator’s assumptions — not a guarantee.
Your own unit, your own land and mortgage register (KW).
Not a share, not a bond — a property.
Every apartment will be a separate unit with its own land and mortgage register (KW). You can sell the unit, give it away or live in it — the operator has no rights to it.
A unit with its own register can secure a mortgage, and the rental income can cover the instalments. We will gladly help you find the right financial product.
You sell whenever you want — with the tenant in place, too. You can also give up the operator and let it yourself or move in — the model is an offer, not an obligation.
Buying privately or through your business? You are entitled to a full VAT refund. We help with the whole refund process from A to Z. How it works step by step →
Buy instead of renting. The holidays will pay off the year.
Parents of students in Olsztyn pay for a room or studio rental for five years. Once their studies are over, nothing is left to show for it. Here it’s different: the student lives at the foot of the castle during the academic year, and for the three months of the season the unit works. A flexible approach lets you try out what works better for you: managing it yourself or with us. Want your own second home? That’s no problem either — you can still use all the amenities.
We don’t force our model on anyone.
You can live in the unit, let it yourself, or hand it over to the operator. You make the decision, and you can change it at any time. The benefit of the whole scheme is access to the building’s ecosystem: automatic check-in with no reception desk, a laundry room, a sauna, a restaurant, a common area, hotel-standard cleaning and linen, joint marketing and booking platforms, one operator for the whole building. The commission is fixed — 15% of revenue for every unit, with no hidden fees — and it covers comprehensive management of the apartment: from photos and listings, through finding a tenant, to cleaning and settlements.
