Overall we really enjoyed our stay of five nights, great value for a large unit with three bedrooms and two full bathrooms. It was really clean, and had nice cotton linens for the beds. The place is a bit beat up, the door to the basement is partially broken, chipped paint, scuffed floors, no dressers or night tables, that kinda stuff but still good value. There wasn't a coffee maker or french press which was unexpected as the ad says there was one, we drank instant coffee which was ok.
But the reason for only four stars relates to fire safety. On Mar. 16, before we arrived, there was a major fire in old Montreal and multiple people died in AirBNBs because they were trapped in units without proper emergency exits. I noticed the basement bedroom/living room in this unit also has no proper emergency exit if there is a fire. The windows are far too small for an adult to fit through, which you can see in the pictures. The only way out is upstairs. Be mindful of that when booking.
