Great place to stay! The room is very clean and comfortable! Alfia is an amazing host, easy to get a hold of and always responds quickly! She was very understanding and provided us with any info/explanation we required.
The location is central, and within walking/biking distance of Old Montreal, McGill Campus, Museums and Jean-Talon market- not to mention great restaurants and bars. The stay is on a busy street so it does get loud at night, but this is easily blocked out with a little ambient noise from the fan.
Be warned, it can be very difficult to find parking in the area. I recommend finding a spot to keep your car for the entire duration of your stay and using Bixi bikes to get around, there are tons in the area!
