This AirBnB is a blast - esp. if you're in Biarritz for surfing. Check the other reviews for hints regarding the best fearture of it. The view is mind blowing.
Dörte & Thomas were very helpful and friendly. Everything was very uncomplicated and convenient. The description is very accurate. Boards included are a reasonable collection (soft top, NSP-style stuff in various sizes) from what you would find at any board rental place at the beach. So that will save you money if you would otherwise rent a board.
The place is a gem. Period.
