I had a great stay at the B&B Cartier. I was in Montreal the entire week of Labor day. This was my first trip to Montreal, Richard was very helpful with reccomendations on where to go and places to eat. The B&B is very convenient just a minute or 2 walking distance from the metro and about the same distance to all the action on St. Catherine's. The rooms were very comfortable and nicely decorated plus free wireless internet. The only warning I have is not about the B&B. If you decide to get a week Metro pass keep in mind they are valid from Monday to Sunday only, it doesn't start from the day of purchase like in most large cities i've been in.

Had an absolutely great time here. Right off St. Catherine's, but no street noise (even though we had the front room). Very convenient to metro and bus station. Pickup service from the airport was also a very welcome extra, well worth the cost.

Richard is certainly quirky, but very friendly and welcoming, and quite helpful with advice on what to see and do in the city. Breakfast (self-serve) was more than adequate (although one morning I noticed a little mold on the croissants), and the little garden was a delightful place to linger over breakfast or an afternoon glass of wine. And with the ample refrigerator available for guest use, we were able to pick up fruit and cheese at Atwater Market for such occasions.

The shared bathroom was spotless at all times, towels are big and soft, the bed was comfortable. All in all, a great place to stay, and I would definitely go back.

Meant to write this a few months ago, but here goes.
A group of 6 of us stayed here for 12 nights from the end of July. We had 2 couples upstairs and 1 couple downstairs, all of us had a fantastic time and will return to Montreal and this B&B whenever we get the chance. The 2 upstairs rooms have their own private facilities and they share a common (well equipped)kitchen, Richard even shows you how to use the (fresh) Coffee Maker. All breakfasts are only continental, and you get it yourself so to speak, but there is a big range of stuff to choose from.
The down stairs rooms are smaller, and share 1 bathroom/toliet, they also have a downstairs kitchen they share as well. The downstrairs rooms are smaller, and cheaper, so are better for the more budget conscious, which suited me perfectly.
The location is great for Rue St Catherine, literally 1 minutes walk away, and also for Papineau Station, again 1 minutes walk away, there's a great Supermarket next door to the Station and a range of reasonably priced restauarnts close by as well. You're not near the CBD, City or financial area here, but that's why you stay in this area, it's a great spot for nearby nightlife.

A great B&B in a good location. Just round the corner of the gay district and metro lines.

The hotel was very clean and comfortable, with very clean decor (modern/stylish feel). The room was large with a big double bed - although the place only has a shared bathroom, it was kept very clean (looks almost new '06). Breakfast is 'continental' style - cereal, coffee, orange juice and there was a few croissants out whilst we were there.

The host was very interesting - initial impression was of typical abrupt Frenchman, but he was actually very warm and helpful.
