We had a really good time in Biarritz. The airbnb is very good located. The interior is quit cool, but its more a holiday flat than an airbnb, because it doesnt seems like there are usually people living. Thats why its a bit more unpersonal than the other airbnbs I knew and you have to bring your own towels and so and clean eveything after your stay.
Nevertheless the communication was perfect and the equipment of the airbnb is good. You re super fast at the beach and really in the center of biarritz. Everything was clean too.
