I can't recommend Sylvie's place enough! I spent a solo month in Montréal while researching at McGill, and was so excited to book this flat. It is as beautiful, romantic, and comfortable as it looks! The bed was incredibly comfy, the light coming through the leaves in the window in the mornings is gorgeous, and the bathroom is very spacious! The water pressure in the shower was wonderful, lots of room for storing clothes, and Sylvie even included a two-ring hob for me so I could cook while I was there. The flat is fully stocked with kitchenware, and you're able to do laundry just outside the room.
You absolutely can't beat the location--you're only one (long) block away from Mont-Royal, but the street is quiet and so charming. I loved sitting out on the balcony and playing my guitar or reading. They even have an adorable cat who came up to sit in my lap once! It's very close to both the Laurier and Mont-Royal metro stations, though I enjoyed the 50-minute walk to McGill through Plateau and Jean-Mance park very much.
In short, this flat is picture-perfect! I hope to stay again! :)
