Considering the hotel's four-star rating, we wondered why our bathroom mirror was hanging practically off the wall, loose from its mounting, and why there was a slight mouldy smell in the bathroom (from the drains). We expected better. However, the staff was accommodating and generally friendly and the room was otherwise extremely clean. The bed was also very comfortable and the Sunday brunch buffet was well presented and tasty. Maybe you should ask about the exact location of your room. They put us on the first floor, on the level with AC units, which were a little noisy during the night. Keep in mind that this hotel is probably designed for business travellers and is not so packed on weekends. In general, Mercure is a reliable chain and recommended. The rooms at the other Mercure by the exhibition centre are slightly larger.
