The bed was very uncomfortable. (No mattress, it's foam over a hard plank)
There is 4 bedroom in the apartment. All Airbnb rooms, with a single Bathroom.
It means a lot of noise with people checking in or out at all hours, and when all rooms are booked you have to get in line for the bathroom and dishes. There is not enough for everyone.
Finally, the apartment has seen better days. It does not look like the pictures.
Cleanliness was average, and not so good in the bathroom.
Bad experience overall, I'll book another AirBnB next time I'm in Montreal.
