We had a fantastic time in Montreal, and having this space was a large part of it. The location cannot be beat, you're in walking distance to hundreds of incredible restaurants, bars and cafes. The apartment was very clean, and felt safe.
We were well aware that the unit is up 3 flights of stairs, but it was still a bit of a hassle. It was a little warm during our visit so we had the A/C on in the main living area, and used the provided fans in the bedroom.
Our only complaint is that the walls are thin. There was a door leading out to a beautiful terrace, but when neighbors were out there you could clearer hear their conversations.
We had a wonderful time, and would recommend this place to future visitors!
