This place is awesome! The location is perfect -- tons to do around the neighborhood, awesome food and cafes, walkable to downtown and Parc Mont-Royal, and accessible to public transportation. The apartment is remarkably quiet for being in such a busy area -- there's no street noise at all. It is an older building so I could hear neighbors going up and down the stairs or moving around in the apartment above, but they were generally respectful and quiet at night so it wasn't an issue.
The apartment itself is very serviceable. I would have appreciated a bit more from the kitchen; it had all the necessities but nothing else. For example the only cutting board is VERY small. And they provided oil, vinegar, salt, and pepper, but no other spices or condiments -- some basic spices would have gone a long way. Still, it was a very comfortable place to stay and had everything I needed to live, work, and eat for 3 weeks.
Hosts were super responsive and helpful as well!
