The Warwick was a great hotel, right in the heart of Montréal. My sons truly enjoyed the pool and, especially, the terrace hot tub (in 9F-degree weather!). My husband and I enjoyed the sauna instead. The staff was friendly and efficient, and the room was a good size, comfortable and clean. The only observation is for the bathroom. Even though it was clean and well sized, there was no room to put anything, other than very little space around the sink, and on top of the toilet lid. There were only two towel hooks (plus a bar on the shower door) for a four-person room, so it made it feel cramped.
The hotel restaurant, Siam (Thai), was fantastic. Overall, a wonderful hotel.
