The host is very kind and helpful. The space is 5 bedrooms, 3 bathrooms, and a small kitchen. There is no "living space" (no casual seating, no TV, and the kitchen table can sit 4 with a very tight squeeze). The pictures looked pleasant, but the furnishing is quite low end. The front door lock sounds an alarm every time it is shut "improperly". (It would often go off 3 seconds after being shut.) Every bedroom door has an automatic lock, which the host said cannot be disabled (although taking the batteries out works). One of the bedrooms exits to the fire escape, so that door being locked is a fire hazard. This is not an ideal place for a long term stay.
However, if you are looking for a 2-3 day cheap hotel space for 6 to 10 people, and plan to eat out a lot, then this space is great. Very close to the metro, and walkable to U Montreal. The host is very responsive, usually replying to texts within 1 hour. When we asked for more towels etc, he provided them within a day.
