Very cozy, clean and well located flat right by the beach. Perfect for a couple. Host was very responsive.
However we were disappointed that after booking the flat she said that it would cost us an additional 20€ for cleaning services and rental of towels, bathmat, bed sheets etc. She said that this was common in Biarritz. In my 6 years experience with airbnb these basics are always provided. It would have been better if this was explained in the description when booking the flat.
