This a wonderful space with everything you need for a very comfortable stay. We were a group of six. The two bedrooms are huge, and the sofa bed in the living area (that we also used) is very comfortable.
It is easy walking distance to all of downtown and the old town. The waterfront and Mont Royal are also walking distance.
You can access the underground shopping malls/walkways (RESO) from right across the street.
We came and left by train, and this apartment is only a ten minute walk from the central station.
I recommend this place for anybody wanting to explore the city of Montreal from a central location - you will have a lovely haven to come back to each day.
