A genuinely lovely place. The apartment is a good size (we are a couple who stayed) and is well decorated for a homely feel. Lucie was welcoming and generous-- including giving us food from the local market and chatting about Montreal.
I liked the quiet neighbourhood, and there's a beautiful (1 hrs) walk to the Old Town along the canal, which is nearby. Charlevoix metro is a ten minute walk and connects well to the city. Montreal is fast and reliable with public transportation.
If you're looking to be in the city centre, maybe not ideal. Also the property has a microwave, kettle, coffee maker, and sink but no oven or stove top. So depends on what you're looking for but we were very happy.
I would highly recommend both the apartment and the host.
