Louis was a great host and we loved the place! It was cute and clean, and on a street with a lot of great spots. We walked across the street to the Burgundy Lion Pub and Gepetto's Pizzeria for dinner. There is also a Super C (grocery store), McDonalds, and the Atwater Cocktail Club all within walking distance. The metro is about a 6 minute walk away too, and it's a big station (Lionel-Groulx) where the green line and orange line both intersect. It was super easy to take the metro downtown and we bought 3-day metro cards for about 21 CAD a person.
The only things that might be difficult are the parking situation (on-street parking that you have to pay for at a meter or through an app, oftentimes hard to find a spot) and there is only one bathroom for up to 6 people. This was all stated in the booking and they offered to help with parking troubles!
Overall the place was clean, the hosts were super responsive, and the apartment is spacious and modern. Would highly recommend!
