I would rate this hotel 5 stars. However, the mediocre restaurant ( I paid 33 $ for a not too impressive cheese plate and a beer), the bad ratings from other customers were true, fortunately there are many restaurants at a walking distance , however a good 5 star hotel should have a good restaurant as a flagship.
Also, I happened to have bad communication with the reception desk, when asking for some housekeeping services at night to get the sofa bed ready they never came and nobody seemed to want to pick my call... At least they could explain me how to open the sofa... Not very attentive.
On the positive side rooms are very comfy; and the swimming pool, jacuzzi and fitness room on the top floor are excellent. Location is also very convenient, 3 minutes walking distance from the main shopping street ( Rue Sante Catherine) and 5 min from the foodie street (Rue Crescent). All in all, I would recommend it indeed.
