This is a great place if you want to be among the locals. There's nice bars and cafes nearby and within reasonable walking distance. Céline&François provide lots of tourist information and recommendations in a really nice organized binder.
The apartment is well equipped with everything you need. If you have a kid -- there's books, toys and a pack and play/high-chair! Basically if you're a small family, (i.e. parents and one kid,) this is a great place to stay.
The public transit is very easy to use -- there's a bus line that can take you quickly to the metro, but you can easily walk the distance within 15-20 minutes. There's also plenty of Uber drivers in the area -- I never had a problem when I needed a driver.
Céline was easy to get a hold of throughout and communication was great.
I definitely would stay here again the next time I'm in Montreal!
