I stayed in this holiday inn for three nights this December. The room I got was clean and cozy. It's on the main street but very quiet when you sleep.
Pro: The staff were very nice. I arrived at about 9am in the morning asking to store my luggage, and they checked me in!
The breakfast is excellent. There were plenty of fruits, milk/yogurt, bread/cake, oatmeal, pancakes, etc, of different flavor. I didn't try lunch or dinner in this hotel since there are many restaurants in the nearby China Town.
Con: Internet (wifi) is not very fast, but usable.
I definitely recommend this hotel if you plan to stay at downtown Montreal.
