First time in Montreal, First time in a W-
I was completely taken aback by the level of attention given to us through emails prior to our stay, which is why i was surprised upon arriving that attention wasn't nearly as personal. Regardless, the staff is truly attentive, the hotel is a smorgasbord for the senses and it is such a fun room what with the open shower and funky furniture. We couldn't help but feel like we were in a nightclub at all times though- even the doormen look like bouncers!

The Wunderbar is kind of ordinary- with an extraordinary exterior. It's more of a professional crowd on Friday night but then again, it IS a hotel bar. Otto has a lovely martini list and is a quiet bar attached to a pretty restaurant. The barmaid there (we are so sad not to know her name) is precious- a wealth of information, so sweet and so nice. It was such a pleasure to chat with her for our 2 nights there.

The location is very quiet. So close to Old Montreal though and easy to get to anywhere else with cab/metro.

The bed is crazy comfortable, the funky design is great fun- but I would say that it could have been cleaner. There was some gunk in the shower, stains on the walls in the bathroom. It was presentably clean, but not thoroughly.

I stayed at the W Montreal for only one night on a recent business trip. I got a very affordable rate ($179 CDN) on the hotel website for a Thursday night in October.
I absolutely loved the ambience... very young and funky. As other reviewers have noted, this hotel is for the young and for the young at heart. Older travellers might not appreciate the low lighting, the music or the decor, but I certainly did.
The location was great for me... my meeting was in a nearby hotel in Old Montreal. The downtown nightlife is not far away (short cab ride or a 15-minute walk), and the Bell Centre is slightly closer.
The staff was very friendly and efficient. I didn't have any problems, so I can't comment on their problem resolution abilities, but they certainly seemed very competent.
The room was pretty funky. As others noted, the shower and the bedroom are divided by a blue transparent wall. I was by myself, so all it meant to me is that I could make sure none of my socks snuck out on me when I was in th shower, but it would be a nice addition to a romantic weekend away with that special someone. On the other hand, you might not want to stay at the W if you're in town to see a hockey game and are splitting a room with the guys.
Like most Starwood properties, the bed was very comfortable. I stayed on the fourth floor and did not hear any noise from the nightclub in the building (which I didn't go to, but I hear it is an excellent place to see and be seen).
I loved this hotel and would definitely stay there again.

The W certainly meets expectations given its reputation for high style. The rooms are beautiful, with a bit of an edge. Some folks might be put off by the open bathroom plan (large shower has no curtain/door, sinks/bath are in the sam "room" as the bed, large curtain can be pulled around area for privacy - WC does have a door). We were put off by the "nickel and diming" of such an expensive hotel. The reputation allows for a customer to buy anything in the room (furniture included), but the fact that phone calls, Internet, etc. are not only not free, but are more expensive than at less expensive hotels in the are is a little convoluted, in our opinion.

With a special discount available to Starwood members, we'll probably go back, but without, we'll opt for other properties.

The hotel was modern and clean; however, with the black walls and dim lighting might be a little dark for some visitors. The staff went out of their way for us. They are the most friendly staff in all of Montreal. The location was good but not great. Not much night life in the immediate neighborhood; but the Metro stop across the street can get you anywhere in the city in a couple minutes.
