Was in Montreal for a couple days for work and a colleague had recommended this hotel. I'm not generally a fan of the W and this trip confirmed it.
While the hotel itself was nice, service was fine, rooms were decent sized and clean - the entire vibe of the hotel was not for me. The moment you walk in you feel like you are in a club. In fact, the first floor has a club which got really noisy in the evenings. The entire hotel was also extremely dark with dim lighting and contemporary decor. It was just too novel for me and not practical for what I was looking for.
The restaurants/bars in the hotel also closed at odd times. It was hard to find a place to get a drink! I stayed on a high floor but the noise was still quite apparent some nights. If you're looking for somewhere fun and different you can give this place a try but I'm going to pass on this place next time.
