An Airbnb revenue forecast is a month-by-month projection of occupancy, ADR and revenue for one property, set beside comparable listings. Buyers use it to test a purchase, operators use it to check an arbitrage lease, and hosts use it to set targets for a live listing.
What I plan around in Gdańsk: Sopot and Baltic beach season; St. Dominic's Fair; Old Town and WWII museum tourism; Ferry traffic to Scandinavia. Guests I price for: Polish and Scandinavian families on 4 to 7 night summer stays. Where I start: Summer premiums with minimum stays, and long off-season floors.
I set up your pricing with Jarmark Dominikański, Open'er and Polish long weekends as dated premiums, plus week-long family rules in July and August. Airbnb and Booking.com then share the same minimum stays and cleaning fees, so the summer calendar fills cleanly.
The service in general is described on my airbnb revenue forecast page; this page covers how I apply it in Gdańsk.
