I stayed here on my first trip to Montreal and couldn't have asked for a better location. Nearly everything I found to do or see was under 3km from the room. I love walking anyway, so even a bit longer was fine.
The room was compact, very nicely done, and had everything I needed from sockets to a hair dryer and a nice shower. The heating works really well and the bed deserves a special mention. The host has put some careful thought into every aspect of the place. I recommend staying here without stressing about the decision.
Also, while a late check out or storing my luggage was difficult (which is completely understandable; there's no obligation to offer either) they allowed me to work in the lobby before I left. That sorted a lot of issues out for me, so I was grateful.
I couldn't find any washrooms outside of the room and wasn't sure where to get assistance besides messaging on the Airbnb app, so if you're someone who likes prompt contact, you may notice it, otherwise everything is just great.
