Take this review with a grain of salt! My wife and I hope to visit in future years.
635 Grande Allee is a great place to stay, as long as it's not the last weekend of the Winter Festival. It was very inconvenient, being 100 yards down the street from the 2 large activity areas of the festival. It is unfortunate that the plains of Abraham are out the back door. The front steps serve as your own viewing stand for the closing parade if you like that kind of thing.
The location of cozy and unique is incredible....except the last weekend of the winter festival when my wife and I will be there.
