An Airbnb pricing strategy is the set of rules that decide what each night is worth: base, minimum and maximum prices, seasons, events, minimum stays, gap nights, last-minute pricing, length-of-stay discounts and channel markups. The tool applies the rules; the strategy is what makes the tool worth having. Smart Pricing is not a strategy, because it optimizes for Airbnb's fill rate and knows nothing about your events or other channels.
What I plan around in Bilbao: Semana Grande festivals; San Sebastián Film Festival; Pintxos and gastronomy tourism; Guggenheim and surf season. Guests I price for: European and North American couples on 2 to 4 night stays. Where I start: Festival premiums, summer rates, and Basque tourist-flat compliance.
I configure your Airbnb and Booking.com pricing with Semana Grande, Aste Nagusia, Jazzaldia and the Film Festival loaded as premium dates, minimum stays tuned to festival weeks, and a winter strategy built around gastronomy weekends and the Tamborrada rather than steep discounts.
The service in general is described on my airbnb pricing strategy page; this page covers how I apply it in Bilbao.
