Passable

Liked: The location is good and bad at the same time. The good thing is that it is located in close vicinity to the Old Montreal and Notre Cathedral, you can literally walk to many iconic Montreal places without using public transport or taxi. The bad thing is that the place seems to be very popular among local hobos and marginal people. You can see them gathering all around the place and communicating loudly during night hours. Breakfast is pretty humble, but croissants are very fresh. The room was not big at all, but was clean.
Disliked: The room was ridiculously small for 4 people (in fact it was a 1-person sized room at best). There's no way to walk around the room unless all the other people sit still on their beds. Sitting is another problem. 2 out of 4 beds are floating bunk beds, and the space between the 1st and 2nd levels of beds is very narrow. The fact that they decided to make lower-level beds very tall (taller than you would expect to see in hotels) leaves like 0.5m of space between the ground and a floating bed. So there's no way to sit on the ground bed, you can either lay flat or half-sit in the fetal pose. Beds themselves are quite comfortable, even though you bump your elbows or other limbs against the upper bunk, every time you roll in the bed. Overall it felt more like a hoStel experience rather than a hotel, and in my opinion, the room wasn't worth the $150/night that we paid.
