No complaints from me - great location - the Metro is literally in the basement of the hotel and there is a Starbucks on site as well, in addition to a bar/restaurant and multiple gift shops.
The front desk staff was very helpful in answering our questions and getting a pizza delivered to our room for late night munchies.
I was impressed at how extensive the Fitness Center was, but thought the equipment was outdated. It was also a bit confusing to get to - from the signs it looks like you have to walk through the spa (which you do) - but that seems confusing and you second guess yourself.
We were on the 29th floor so we had an amazing view and I thought the rooms were very nice and comfortable.
Would definitely stay here again if I was ever in Montreal.
