Frédérique was great! I got in before the usual check-in time, but she got the place ready to go early and even waited extra for me when I got lost walking to Biarritz from the train station (45minute walk, easier to take bus). This space was clean, bright, welcoming, and five minutes from beach easily. I know she owns another space even closer, but this place has a great location too. Has a cool, little kitchen and great sized bathroom with shower. I was only there two nights but I was tempted to stay longer after seeing how great it was. Wish I did.
Biarritz is a great little town. There's no wifi at the apartment, but it forced me to get out and see all I could in the city. And if need be, there's cafés all around with free wifi. Definitely coming back.
