Vivian & Rocco's place was easy to find from their instructions, and in a central location that was a good base for exploring all the areas of Montreal. The reason for the 2 stars is because of one big issue, plus a few smaller ones. We unexpectedly had an entire day (7am - 5pm) without access to running water in the apartment. We only found out about this water disruption from a note on the door to the apartment, and when we got in touch with the hosts about it, they said they forgot to tell us. We explained the inconvenience of this - we would have to get up at 6am in order to use the shower/toilet/taps before then needing to spend the whole day out of the apartment without having it as a space we could use for the bathroom (seeing as access to public toilets isn't as common now with Covid), essentially making it unusable for part of the time we'd paid for. The hosts said they would supply us with water for the duration, which we gratefully accepted, but when asked if we would be compensated for the disruption, they ignored the message. They then also never supplied us with any water. We ended up having to go through airbnb's support system who determined we were in fact owed compensation.
That incident aside, I still probably would not recommend this rental. The hallways in the rest of the building (and the elevator) had some sort of temperature problem and were extremely hot and humid at all times of the day. The hallway floors outside of the unit are also quite filthy. That may not be the responsibility of the hosts, but it was still unpleasant. There was also no cold tap water (luke-warm at best), the fan in the bathroom did not work, and the water pressure in the shower was pretty weak. Some of the dishes that were stacked in the cupboards were dirty with old oil / grease, and the paper sugar packets provided must have gotten wet previously because all the sugar inside was solidified into a little brick, again a bit unpleasant to not know where your sugar has been. None of these things alone are deal-breakers but the accumulation of everything really made us feel like minimal care has been taken at this property. First and only bad airbnb experience in almost 10 years. I'm not usually one for giving a bad review, but this was a very disappointing experience. No one wants to spend their first short holiday in 2 years having to deal with this sort of thing.
