I stayed here a little while back for a three day visit to Montreal and it stands out as the best hotel experience I've ever had.
The staff were accommodating, helpful, and went well above and beyond. Not only did they make last minute reservations, offer (excellent) restaurant recommendations, and help us navigate the metro... When we told them that we were on a hunt for amazing and unusual bottled beer to bring back to Ontario, they got busy on the internet trying to find the best place in town for us to search.
The location is great, in the heart of old Montreal (and my room had two big floor to ceiling windows that I could open and gaze out). The building is lovely, our room was immaculate, comfortable, clean, and creatively decorated, which is such a nice treat in a ritzy hotel. I adored every minute of my stay here.
