Stayed here for 3 nights. I used my Marriott points and this one was the cheapest option among all Marriotts in Montreal (minus the one by the airport, which wasn't an option). Just outside of DT of Montreal, 2 blocks from St. Catherine Street. Service was nice, but room needed some renovation. Breakfast was average. First day I had a major issue with a cigarette smoke coming from bathroom's air duct. I complained to front desk and it was taken care of. Overall, not bad if you are on budget.

The Residence Inn Westmount is on a residential and quiet street a few hundred meters from Westmount Mall and Atwater station of the Montreal metro. It is considered to be just right outside Montreal's downtown. If you're fine with that, then the Residence Inn is a nice option.

Location: 5 minute walk to Atwater station, and to a mall that has several restaurants, a huge supermarket, and the usual shops;

Room: A typical serviced apartment with kitchen facilities
Breakfast was free and respectable.

Service was topnotch.

I stay there for the weekend. I received an upgrade for the room to a one bedroom apt. The hotel was renovated and the rooms looks modern and are clean. The kitchen is well equipped. They have a pool, gym and sauna on the 20th floor. The location is quite and close to the main downtown core. The internet is free and the buffet breakfast is included in the rate. Stay in the room from the 10th floor and up and you will have amazing views of Montreal.

Good location, quiet although not far from downtown Montreal. Spacious, we had a bedroom and a livingroom suite with a perfectly equipped kitchen. Don' t worry about grocery shopping, the hotel does that for you, and they only charge you the cost of the groceries. Great breakfast and a couple of nights a week they offer soup & salad or something else light at dinner time - perfect if you have had a heavy lunch. There are only two lifts, too few when the hotel is fully booked, you need to have patience waiting for the lift. Very friendly staff, right from check-in till calling and helping out with the taxi to the airport.
