I stayed here as a student for a semester (~4 months Sep-Dec) and had a wonderful time. Carol is a great host who will quickly respond to messages but is also never intrusive and lets you have your own private space. The place is spacious enough for one or two people, and it comes equipped with everything you would need, except maybe a TV if you're that kind of person. The location is excellent, central enough to reach many places downtown on foot, and also a 5 min walk from the biggest Montreal metro station, Berri Uqam. Would highly recommend staying with Carol for your visit to Montreal.
