Not too big, not too small.
Perfect size, and the staff is fantastic. They speak to you as if they know you; and they make sure that you feel welcome in their city.
The hotel itself is very nice, very stylish and comfortable. The room size was excellent, and one of the most comfortable I've stayed in.
I will make an effort to book here anytime I visit Montreal. Probably one of my favorite places to stay in all of my travels.
