I stayed at Katherine's for a full month while I looked for a permanent place in Montreal. The location of this place is really spectacular. It's located Right by Parc La Fontaine and maybe a 5 minute walk from Mont-Royal Ave so it's really convenient.
The nearest Metro station is Mont Royal which is about a 10 minutes walk.
During my stay I had some issues. I think it's important to note for anyone who might be travelling for work. The WiFi in the apartment is really awful. It's quite slow even though it's listed as "High Speed" (this is pretty normal in Montreal where people have access to 300MPS and gigabit but use 5-10MPS) I found the connection very spotty and it would often drop out during video conference calls or just not connect at all.
The bed is just a futon. I need to stress that because it's not apparent from the photos but it's quite uncomfortable to sleep in for a prolonged period of time.
The toaster didnt work.
Unlike a lot of AirBnBs I've stayed in, it was fairly barebones in terms of amenities. There was no handsoap in the bathroom when I arrived so I went and bought some and only two rolls of toilet paper to last me for the full month. The only thing in the kitchen was oil (no salt, pepper, sugar etc.) The coffee maker listed in the ad is just a Moka Pot fyi.
During my stay my girlfriend surprised me with a visit showing up unexpectedly one night for a one week stay. Before I had time to message Katherine to inform her there would be another person staying at Air bnb for a week she had already sent me a message saying she knew someone was with me and demanding I pay the extra amount for them to stay for a month. Perhaps a miscommunication, but nonetheless it felt like an accusation that I had attempted to hide this from her.
The downstairs tenant could hear me walking around due to the walls and floors being very thin and complained to Katherine about the "noise" (of my foot steps) who in turn complained to me telling me to keep my unit quiet. This I did take offense at, as I think it's perfectly reasonable to be able to walk around an AirBnB you're paying for at any time of day or night. I think this might be a case of the downstairs tenant being resentful that there is an AirBnB in the building, which isn't Katherine's fault.
All-in-all compared to other places in Montreal for a long-term stay this place is okay and only really pulls ahead because of the location. However the presentation leaves something to be desired and I would say that the price for a single night is far too high given what you get.
