Pros: Very cute apartment, fantastic location, no complaints about the apartment itself.
Cons: There's an addition fee for "new linens" that varies from 20-60 euros that's required to pay in cash, and it's pretty unclear what the cash is for. We did not have cash on hand (typical American move), and the town ran out of cash and it ruined our last day in Biarritz trying to find cash. After lots of back and fourth with the host manager, she allowed us to pay in paypal (would have saved several hours if she let us do that up front).
Cons: The other con is the general lack of transparency with what is included in the airbnb fees. When you're paying 50 additional euro, and cleaning fees are usually included in airbnb price, you expect someone to take out the garbage (we were two girls, staying there for 3 nights, the apartment was in good shape). The host manager was quite rude and insisted we clean the apartment, and go to the recycling down the street and empty the trash... pretty rude experience.
Overall, great place, but there needs to be more transparency around the fees for this place, or else it makes for an uncomfortable last day.
