As someone who grew up in Montreal and now comes back from time to time for a visit, I must admit that I never knew this place existed. It's a tiny boutique hotel in the downtown core, where I've stayed a few time (admittedly, through bookings on Hotwire). The rooms are spacious and clean; the staff are helpful, and the complimentary continental breakfast is a nice touch.
As a small hotel with only a few dozen rooms, it's got a funky vibe; the rooms all appear to be different - so there's none of the feeling you get in some of the larger chains where you won't even know what city you're in when you wake up, since all the rooms across North America have the same, cookie-cutter vibe. Look at the photos here on Yelp for an idea of what the rooms are like.
It's a hidden gem in Montreal that I'd recommend.
