The biggest pro: this space is HUGE for larger groups. There's literally like 2 separate units on a floor that you have access to. Additionally it's in a really great, central location (assuming that things in Montreal are open). Also the 1 free parking space was convenient
This place was also extremely quirky - the walls were incredibly thin (like you can literally hear everything in the next room), floors slanted, etc. So this is definitely a very barebones place to stay in, but it was perfect for our group who just wanted just to stay in and relax.
