Mercure Nice Centre Grimaldi

We booked 3 rooms for two nights - 1 classic and 2 premium. At checkin, the lady tried to tell me she upgraded me from classic on two of the rooms because I am Expedia Gold. When I told her I booked and paid for 2 premiums and a classic she said she can't upgrade the classic to premium because they are overbooked. It was extremely disappointing as we are Gold members entitled to at least one upgrade when available and also the 1 classic and 1 premium rooms were having birthdays exactly on the day of the checkin. We normally would have expected at least a glass of wine per room (if not a bottle) for the event, and at least one of the rooms to be upgraded. Instead, we got NOTHING and our "premium" was a mansarde /attic small, dark , cramped room, with dump "everything" ( carpets, linen, towels) which smelled terribly. There was a very nice young guy at the reception, which helped us with vases for flowers we bought, etc, but nothing more. In all, a very poor experience and the hotel is in dire need of renovation and updating, as their towels are almost transparent from overuse and their carpets were last changed probably 10 years ago. We didn't try their breakfast because it costed 19eur/person/day - when one could have walked and got fresh coffee and a croissant for a 3rd of the money -, but the other two rooms ate there as they had children, and they didn't find the pastry in the 2 days they ate, and the breakfast choices were just basic. Expedia starts to dissapoint!
