An operator for a fixed 15%.
All your letting in a convenient dashboard and on your phone.
You buy an apartment with a ready-made earning model, without having to manage the letting yourself. During the academic year we let it to students and in summer to tourists, making the most of both seasons. For a fixed commission of 15% of revenue we take care of everything: finding tenants, bookings, cleaning, laundry and statements. You keep track of revenue, occupancy, payouts and documents in real time in the app and your dedicated online panel. You don’t have to live in Olsztyn, look for tenants or hand over keys. And whenever you want to use the apartment yourself, you simply book the dates for yourself. The property remains yours — we make sure it pays its way.
The app is already on the App Store (iPhone, iOS 16.4 or later) and on Google Play (Android). The app’s interface is currently in Polish.
You don’t need to be on site
to keep the letting running and earning.
The owner can see the unit’s figures from anywhere. Tenants and guests enter the building by phone at any hour, and the operator runs everything from a single panel. No reception, no key handovers, no “so how are we doing?” phone calls.

Service prices in the app are examples; we will publish the final price list before letting begins.

You buy. We let it.
The app shows you everything.
The unit is delivered in shell condition, with a turnkey finish at 3 000–4 000 zł/m² to the building’s standard — do it yourself or with us. Your own land and mortgage register (KW) after the building’s handover.
One fixed fee: 15% of revenue. You can give up the operator — and go back to letting it yourself or move in.
October – June: students on a fixed monthly rent. July – September: Old Town guests by the night. One price covers utilities and internet — the tenant gets a single invoice.
Revenue minus commission: a statement and a report in the app every month. You invoice the operator for your share — monthly, quarterly or annually, as you prefer.
You stay in the model, let it yourself, live in it for part of the year, or sell the unit together with the tenant and the agreement. It’s your property.
Everything that takes up the owner’s time.
- Listings, photos and booking platforms (Booking, Airbnb, long-term letting portals)
- Finding and verifying tenants, tenancy agreements, deposits
- Check-in and check-out with no reception desk — codes, QR, NFC, at any hour
- Cleaning, hotel bed linen and towels, laundry on site
- Minor repairs, inspections and day-to-day contact with tenants
- Statements and a monthly report for the owner — in the app
- Upkeep of the common areas: restaurant, laundry room, sauna, playroom / reading room
- Joint marketing for the whole building — 38 units under one brand
No hidden fees.
Apart from the commission, the owner bears the costs of the property itself: property tax, unit insurance and service charges for the common parts — we will give their amounts after the building is handed over. We will go through the details of the operator agreement at a meeting.
Estimated net ROI 8,0–10,3% with the operator,
9,4–12,2% commission-free.
With the operator, you pay a fixed 15% and you do nothing. If you let it yourself, you keep all the revenue, but you take on the management — guests, cleaning, laundry, booking platforms — yourself. A representative example, the assumptions for every unit and the calculator are on the investment model page. These are estimates, not a guarantee.
We don’t force our model on anyone.
The operator model is an offer: the same fixed commission for every unit, with no hidden fees and no obligation. You can let it yourself, live in it, or mix the two — the building’s ecosystem and the app are available whenever you want them.
