I stayed in this hotel with my girlfriend for 4 days and we had a great time.
The hotel was very clean and the staff was very nice and helpful whenever we needed. The room was quite big and very comfortable, with high speed internet access, cable TV, air conditioning and even had a full kitchen which we ended up using to cook dinner one night.
They also offer a delicious breakfest buffet and on some week days they have a sort of a "happy hour" with snacks in the late afternoon/early evening (everything included in the price).
Another good thing is the hotel location, it's a 5 minute walk to the Atwater subway station.
When we booked this hotel we thought the price was very good for the time (August) and for the services they provide, so I'd definitely recommend this hotel!

The hotel room was clean and good sized, with nice beds, a flat screen TV and a built in ice maker in the fridge. Couldn't hear any noise from the rooms next door. Major problem is the size of the bathroom, which was very small for a hotel of this rating. I had to squeeze against the sink when closing the door to avoid brushing against the toilet. Ugh.

On the the bad stuff. The kids in the room directly above us flooded their bathroom and resulted in water pouring down into our bathroom. This resulted in flooding our bathroom and the need for cleaning staff to come in, suck the water out and then use fans to dry. The whole process would have taken about 3 hours with an additional 2 or 3 hour wait before the fans would be in the room for a total of 5-6 hours of wet, damp bathroom including 3 hours of having a loud fan roaring in the room.

Industry standard is to move us to a new room, when one is available, which they didn't automatically offer to my friend who was in the room at the time. We weren't moved until I returned to the hotel and marched to the front desk to demand a new room. This is unacceptable for a hotel of this quality, particularly when empty rooms are available!

Next, the parking lot for the hotel is a) not owned by the hotel, which means b) any damage inflicted by the valet parkers are not the hotel's responsibility. This was not made clear to us, as we arranged for parking with the hotel not the bloody garage. The receipt even has the Marriott Residence logo on it! Needless to say our car was scratched, which in hindsight should not have surprised us as the garage was very, very tight.

Would I stay here again? Nope.

My wife and I stayed at the Residence Inn October 24 - 26, 2007. She was there to play and I was there to work. I suited both of us admirably.
The rooms are a bit on the old side, probably why this is a 3 star as opposed to a 4. The room was a good size and with a fridge, stove, and microwave, had everything we could want. The amenities are good. The buffet style eats are excellent in the morning and again between 4 - 6pm. The hotel is centrally located, within 1/2 a block of thousands (or so it seems) shops underground. It is a 15 minute walk to old Montreal and the shops and nightlife there.
The staff were outstanding. Cheerful and helpful. I would recommend this to anyone visiting the area.

room is clean. free internet service. that's the only good thing i could say to this hotel. free breakfast is upsetting since they ran out of everything- waffles, cereals, oj, banana, etc. u asked the manager and he tells u he can't do anything since they don't have the supplies anymore!!!! so, if u want to eat, u have to be there as early as u can. they're supposed to serve till 10am. but, by 9 they won't replenish anymore. go some place else!
