Crucial info: The Days Inn the next block over has a bar. This one doesn't.
That aside, the relatively inexpensive and massive suites easily and comfortably sleep four people (for no additional charge!) with the pullout sofa. Our showerhead dripped, and the televisions are the old-fashioned tube variety, but the beds were comfortable enough. Oh, and there was weirdly one day when they didn't come to clean.
The free continental breakfast was exciting every day though, with fresh cinnamon rolls, apples and bananas, English muffins, bagel, bread, oatmeal, four varieties of cereal, a pancake-making conveyer belt, yogurt, hard-boiled eggs, bacon or sausage, plus some egg dish (scrambled or omelettes--beware that they may have meat though!).
Free wifi in the rooms, a fitness facility we didn't get a chance to check out. We were there for a convention at the Palais de Congres, and the walk was easy and quick.
The 747 bus takes you to and from the airport, but make sure you're paying attention to the stops, or you may end up at the terminus in the dark of night, sad and alone in Montreal. In other news, a cab will cost $38.
Oh, and there's no room service. You do have to venture from your bed to be fed.
