Our stay, although very short (we were just passing through), was very good. Our studio was very nice, spacious, and comfortable. The fact that they have a mini-terrace is also a plus. The prices, for the area, are quite affordable. The staff is very friendly and speaks Spanish. Plus, the center is a very short walk away, and there's a public parking lot right next door (you'll have to be lucky, though). You can also reserve parking there in advance, as they have three (two outdoors and one covered).
The only downside is that the beds weren't made, and the top bunk was very uncomfortable.
Ideal place to stay, the staff is very friendly. The professionalism of the reception staff is to be highlighted, we had to deal with Céline who was very attentive and gave very good advice for discovering Saint de Luz and the surrounding area. A big congratulations to the whole team.
