We had a great time staying at the house.
Our room had everything we needed, the bed was really comfortable and everything was very clean. The shared space was clean and way bigger than we expected.
We only briefly met the hosts but whenever we had a question they responded immediately to our messages.
To get downtown it takes about 30 minutes by transit or 15 minutes by car from the house but the place is only a few minutes away from the metro station so it is still easy to get around.
We would definitely recommend Marc and Chrisella's place and if we ever find ourselves in Montréal again we would love to stay at their place again.
