The apartment is very spacious and clean. Our family of 6 was very comfortable. The place is fully renovated (on a budget) and has most necessities for a comfortable stay.
The location is perfect if your goal is to explore downtown Montreal and enjoy the night life. It is located in the heart of restaurant district on de la Montagne. Parking is convenient. It is, however, a first floor apartment, so noise till the early hours of the morning is common. It also located just over 3 restaurants (it shares en entrance with one of them), and the smell of food and fish (2 are sushi restaurants) is also noticeable.
The owner/management team is responsive to messages on the VRBO app. We had an issue with the heat, and one of the rooms was not habitable due the temperature never rising above 17C, but I am assuming this will be fixed.
