i haven't stayed at Zero 1 but recently stumbled across it when looking at montreal hotels. i'd examine the place closely if you're seriously considering staying there. i was initially impressed with it, based on price and the hotel's website photos: it looked slightly chic. however, i followed-up on trip advisor, where it gets fairly high ratings, and was surprised at the photos contributed by travelers. the place looks clean, but the room furniture looked more like something you'd see in college dorm. again, i haven't stayed there so the hotel may be fine...just wanted to point this out.
