We just got back from an amazing week in Biarritz! The apartment we rented by Hervé is perfectly located in the heart of Biarritz and it's just a short distance to three different beaches as well as to a great variety of restaurants and shops. When we first arrived the apartment was a bit damp, but as soon as we got the dehumidifier working it became much better. The only thing we missed during our stay was a view from the apartment, but as it was so close to the beach and different restaurants and cafes with great views that wasn't really a problem. Hervé was a great and very helpful host! He answered all our questions and even allowed us to stay as long as we wanted on our departure day, as the next guests wouldn't arrive until the next day. That pretty much gave us a whole extra day in Biarritz. :)
I would very much recommend Hervé and his apartment in central Biarritz to anyone looking for great location and a responsive and helpful host!
