Had a great stay in Montréal! The apartment is nicely furnished, has all of the touches that you could possibly need (stocked kitchen, detergent, coffee, etc), and is in a wonderful location on multiple bus lines and around all sorts of great restaurants and shops. We found the public transport to be super convenient for everything that we needed. Beds were comfy.
Note that the floors of the apartment are really very squeaky in all areas except the kitchen. Also, the middle bedroom maybe wasn’t meant to be a bedroom - it has a large double door to the front bedroom that isn’t usable (there’s a dresser in front of it), but sound does still go under it easily. Due to these two things, if you have light sleepers in your party or need a lot of privacy, it might be a problem. However, the other aspects were so exceptional that we still left 5 stars. We had a great stay.
