We were very happy with our stay here. This house is conveniently located, close to the busy parts of Montreal downtown (e.g., less than 10 minute walk to rue Crescent). The Guy-Concordia Metro station (blue line) is about a block or two away, very close. There also two separate BIXI bikeshare stations close by, which is what we ended up using a lot to get between downtown and Vieux-Port.
The house itself had plenty of room for our group of 7 adults. There are three beds and a couch/living room that you take a good flight of stairs down to get to, so keep that in mind in case stairs is an issue for children or those with movement issues.
The washer and dryer is located in the kitchen and seem brand new. Very convenient feature to have.
Audrey, one of the hosts, was very friendly and replied quickly to any questions we had before and during our stay.
