We stayed at this hotel due to its great proximity to the U.S. Embassy. My husband had to have his visa interview there and it was a very quick walk (literally around the corner). Because of this, we were able to be the first people in line at the "secret door" (that you'd never know actually takes you inside the embassy).
The hotel had a business/internet room which was perfect for our last minute panic searches (I'm telling you, a lot goes through your mind the night before a visa interview) and also they were good about accepting (and getting to us) a last-minute overnight package which included my brother's birth certificate coming from the U.S. (we had forgotten it in our visa app and the visa would have been denied).
The complimentary continental breakfast in the "breakfast lounge" was perfect for us as we were in a time crunch in the a.m.. Just your standard bagels, juices, cereals and the like.
Also walking distance to lots of food and shops. Montreal has two things for sure, angry frowny faced people and goooood smoked meat!!
