My partner, dog and I stayed at the apartment for 5 weeks and it was a great stay! The apartment is spacious enough for two people and there are two balconies on each end. There is a lot of natural light and the kitchen is decently stocked with cooking utensils. The apartment is also on the top floor of the building so it was very quiet and we never heard the next door neighbor make noise. The apartment is walking distance to lots of things, such as Mont-Royal Ave with plenty of cafes, bars and restaurants, and a 10 minute walk to the metro. The bed is a basic spring mattress so it was okay but might be an issue for someone with a sensitive back (you could check if it has been replaced since our stay as well).
Communication with Muriel was very excellent! At one point we had an issue with the fridge breaking and it was replaced promptly and we were even offered some compensation for groceries that got damaged.
Would definitely recommend this apartment to stay in and we are grateful for the experience we had!
