I stayed there for a couple of nights in September 2016.
For some reasons, I didn't booked directly on accorhotels.com, but on booking.com and showed my (at the time) gold LCAH card while checking in. I immediately got upgraded one level and issued a drink voucher (which I didn't use). Obviously no point were credited to my account due to the booking not being made directly with Accor.
I have very good memories of the restaurant, I'm actually considering rebooking there just because of the food.
