Nice apartment close to the cote des Basques Beach and close to the center of Biarritz. The caretaker was very responsive and helped us to have a good stay. The apartment has a good price quality ratio.
There is free street parking available 5 mins walking from the apartment just beyond the Bibi beaurivage area, you will just need to look for it a little bit but it was very easy to find free parking for us (we were staying at the end of October)
