John's building is in a fantastic location for anyone looking to enjoy the Montreal nightlife. My group of 4 was very comfortable in the space. We attended a concert just down the street, and it was great to be able to walk there and back. The check-in was super easy and John was quick to respond to any inquiries. He even got us on the guestlist for a night at the club around the corner!
Just be aware that from about 10pm - 3am on concert nights, this place is LOUD! I believe it shares a wall with the concert venue, so you can hear (and feel) the show going on next door. All in all, a fun experience in Montreal!
