Good escape in a quiet neighborhood just a 10-minute walk from the center and a couple minutes away from a "mini-center" on the other side, with quick convenient options for "bons produits". Interior was excellent for our family needs, especially the kitchen area. Oihan did a very good job of guiding us in and out, a mostly automated process (in a good way).
Just a quick tip for first-time visitors with a car -- its very hard to find parking spaces in the area at busy times of the year (like the rest of Biarritz) so be warned!
