Our room was nice and well-appointed. The hotel puts a beach bag and two beach towels in the room, so you are ready to walk to the beach. The lobby is beautiful, with plenty of space to eat, drink, or relax. On some nights, there is music in the lobby. Biarritz is hilly, but as long as you don't mind hills, you can walk anywhere you need to go in the city. If you have a car, parking is available on-site for a small fee. The pool is nice, with plenty of seating, and a staff member periodically comes out to take your order. The staff is eager to help answer any questions.
Negatives were a very leaky shower and an in-wall, not very powerful hairdryer, although I believe you can get a better hairdryer upon request.
