I spent two nights in Mark's apartment with my boyfriend, and I would definitely recommend that place! It is well located, in Le Plateau, close to some nice restaurants, and you can reach the famous Mont Royal on foot!
The apartment is clean, there is a small balcony if you want to have a sunny breakfast and you are surrounded by several music instruments since Mark is a musician ! We didn't have the opportunity to meet Mark, but I had several cintacts with him before and during our stay in Montreal, and I can say he is very reactive and helpful! Thank you Mark!!
