Very nice stay for the price. Everything was as described in the listing; the bunk was reasonably private, well cleaned, and the common facilities were excellent. The staff were all accommodating and friendly. Also, it’s really central so you can easily walk to most downtown attractions in Montreal.
Just note that the bathroom will only be as clean as you and the other roommates keep it. Same goes for the room floor. Everywhere else is kept super clean and tidy by the staff.
