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 Coimbra: University of Coimbra; Queima das Fitas student festival; Joanina Library visits; Coimbra fado tradition. Guests I price for: visiting parents and cultural travellers on 2 to 4 night stays in the Alta university quarter and the Baixa below it. Where I start: the academic calendar as the real seasonality driver, a sharp Queima das Fitas peak, and AL registration for lets near the university.
I set up your pricing so the student festivals and graduation weekends sit in their own bands, with minimum stays that match how parents and alumni travel. Weekly rates for visiting academics and hospital visitors fill the gaps, and Airbnb, Booking.com and Vrbo all follow the same rules.
The service in general is described on my airbnb revenue forecast page; this page covers how I apply it in Coimbra.
