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 Cartagena: Walled City and Getsemaní tourism; Colombian long weekends; Wedding and group travel; Rosario Islands day trips. Guests I price for: Colombian and international travellers on 3 to 5 night stays. Where I start: Holiday and long-weekend premiums, group-home pricing, and rainy-season floors.
I set up your Airbnb and Booking.com pricing with holiday minimums, festival and Holy Week blocks, puente premiums and a capacity-based rate for group houses. Extra-guest fees, deposits and house rules match on both channels so a group booking never undercuts the plan.
The service in general is described on my airbnb pricing strategy page; this page covers how I apply it in Cartagena.
