Only stayed for one night, but got a lovely room with a fantastic view of the sunrise.
The room was modern and very nicely furnished. The pool, although small, was well maintained and clean.
The restaurant had great food, but the waitors seemed to be absentminded and not very welcoming.
Regardless I would stay at the hotel again (with just 10 minutes in to the center of La Rochelle one do not have to dine at the hotel).
