I was there a night during the summer of last year during a road trip through France and Spain - actually if people are interested I still have a Onenote file with a half-finished review on the hotels during that trip (about 5-6 different Accor hotels including the Mgallery in La Rochelle, Mercure San Sebastian, Mercure Orlean Porte de Sologne, etc.)

From all my stays with Accor it was one of the more underwhelming experiences, despite being the most expensive of our road trip. Definitely far below previous Sofitels I had stayed - imo they should rebrand this hotel to a lower category brand. I had booked using a Suite Night Award and was given a Prestige Suite which was spacious, but it was like 1 level above the lobby with views of the parking. Would have preferred a lower category sea view really.

Breakfast was decent but nothing special. Dinner at the restaurant was ok. I remember being a little disappointed in the cocktails quality.
Reception was good/kind and the woman greeting us was lovely, but other than that I wasn't very impressed with staff.

In my opinion it's one of those old hotels that have lost a lot of their glory. Pool area I wasn't the biggest fan of either. I would likely not stay again.
