I'll start with the positive and it is a big positive. The location is stellar as it is centrally located providing excellent access to all districts of Montreal easily on foot. When booking, I saw only the check-in time of 4 pm. Further, before confirming the booking, the host contacted me and asked me if I had read the "house rules", which I had and took a screen shot of same. After confirmation, a more comprehensive set of rules was sent to me and the check-in time was 4 to 8 pm; our flight arrived at 10 pm. Within one minute of confirmation, I requested cancellation and was met with rigid denial of same notwithstanding their house rules mention NOTHING about this narrow check-in window.
Further, the unit was supposed to be smoke-free which was important to my daughter and me as we have asthma. There were signs of smoking by previous occupants, unpleasant odours in the unit, and horrible odours in the common areas including halls and elevator. There was laundry left in the drier leaving us to wonder if we were to launder sheets and towels. The bath towels were tiny and skimpy. The unit's hall lighting malfunctioned and needed to be reset at the panel circuit breaker. The pull-out couch was horrendously uncomfortable. The common entrance security was lax and not at all locked as it was supposed to be (not the host's fault, but noteworthy for guests concerned about security). The unit lock was finicky and complicated. We were completely unfamiliar with this kind of lock and had great trouble opening and locking the doors at various times. We consistently removed footwear at the unit entrance which is why on arrival we easily detected some sand on the floor of the bedroom. For a unit with such thoroughgoing house rules, one would expect the unit to be better appointed than the above and that "house rules" would include important information like a limited window of check-in from 4 to 8 pm.
