The good things about the stay: the studio is in a lovely location, near to the beach of Ciboure and overlooking a lovely river. The little balcony is really nice. The studio is small but has all the things you need for a stay, although in hot weather the mezzanine bed is a bit too warm.
The less good things about the stay: The agency didn't inform us of additional fees for cleaning (€60 per stay) and bedding/towels (€20 per person) until after I had booked. I was able to buy bedding for less than this price at the E. Leclerc. I think because the cleaning is so expensive the place wasn't as clean as it should be, but it also wasn't bad.
