I had a great experience staying at Mathieu&Martin's studio. They were quick in responding emails before the trip, and very helpful in accommodating our needs. At arrival, they met us at the studio and gave us the basic directions, as well as some suggestions for the local events, which was very nice of them.
The place looked brand new (exactly as advertised) and was very very clean. It was very comfortable and had all the basics that one needs for a short stay.

I would definitely stay at this place in my next trip to beautiful Montreal.
