We ended up waiting until the last minute to book a place for Montreal and were lucky that Audrey's place was available! My family stayed there (two adults, 5 year old and 2 year old) and the space was great for us.
The place was very clean and the AC was a big plus as the weather was really warm during our stay. It was nice to come back to a cool apartment if we needed to.
The apartment is located on a busy street and I was worried that noise might be an issue but we didn't have any problems in that regard. Even with two small kids there were so many great restaurants, shops, and parks within walking distance.
Definitely recommend Audrey's place if you're looking for somewhere to stay while in Montreal!
