We had a great stay at la Surfeuse des Halles, which is perfectly located, steps from the wonderful covered market ("les Halles") and its vibrant social and dining scene. You can walk to all of the major beaches in under 5 minutes. The apartment itself is cozy and nicely decorated, and meticulously maintained. We found everything we needed. It is also very quiet, particularly at night, which is not a given two blocks from les Halles. We found it a bit small for our family of 6, especially with only one bathroom and no outdoor space, but it would be perfect for a family of 4. Sophie was warm and responsive and a great person to work with. The price was high for the amount of space but sadly this has become a reality in Biarritz in August and it would be the same anywhere. Be aware that parking is VERY challenging in Biarritz in the summer and consider not renting a car, or doing so only for a day trip. It is almost impossible to find spots near beaches or in the city center and we were never able to park on the street, which has reserved parking for residents but no assigned spots - we never found one and ended up leaving our car at a friend's house 20 minutes away and never using it.
