I stayed at Erwan's place for 2 nights with my nearly 2-year old daughter. Though the apartment is not designated kid-friendly, Erwan was incredibly helpful and borrowed a travel cot from a friend so that we didn't have to bring one from London. Everything was very clean and well-equipped, and the location is great - walking distance to shops, restaurants, the beach, and a larger grocery store and local market. My only regret was not spending any time on the beautiful terrace as we were in town for a wedding and didn't have much down time at the apartment. I'd definitely rent the apartment again if I returned to Biarritz. Communication with Erwan (with the help of Google translate) was also quick and easy. Thanks Erwan for the lovely stay!
