Vrbo listing optimization is the work I do to make a property rank, convert and price correctly on Vrbo. I rewrite your headline and description for Vrbo's family and group guests, order photos to sell the whole home and tune rules and settings.
What I plan around in Biarritz: surfing on the Cote des Basques and Grande Plage; Fetes de Bayonne; Belle Epoque Biarritz; Saint-Jean-de-Luz and the Basque coast. Guests I price for: surfers and French and Spanish families on 5 to 7 night stays in central Biarritz, Anglet and Saint-Jean-de-Luz. Where I start: peak-summer and Fetes de Bayonne premiums, the Biarritz change-of-use compensation rules that restrict new holiday lets, and a September surf shoulder.
Biarritz sells mostly through Airbnb, Booking.com, Vrbo and Abritel. For Basque coast hosts I set up PriceLabs or Wheelhouse with weekly summer bands, festival uplifts, a September surf shoulder and winter monthly rates, keeping Airbnb, Booking.com, Vrbo and Abritel aligned so French and Spanish guests see the same totals.
The service in general is described on my vrbo listing optimization page; this page covers how I apply it in Biarritz.
