We had a really good time at Michel's place (which is very central!) and Biarritz is definitely worth a visit. Even though we only know very few words in French Michel was patient and communicative answering all our questions and giving us tips for the city. His street is quiet and his tiny dog Emma is very friendly and calm. We would always recommend staying at Michel's!
Merci beaucoup, Michel. Nous avons passé des jours formidables en Biarritz.
