Kay & Matt's apartment is situated in downtown Toronto and connected to the PATH network of underground walkways which was a wonderful respite from the snow in Toronto's colder months. The building is conveniently located across the road from a supermarket which can be accessed via the PATH network without having to step outside!
Check-in was smooth, the hosts were responsive, and the building has 24 hour security on hand. As other reviewers have noted, the apartment is connected to the building's air conditioning system, which is unable to be switched off. This may be an issue for people with sensitive hearing, but this did not impact my ability to fall asleep at night, and I wouldn't deduct any stars for something like this as it is found in almost all apartment buildings in the Toronto area.
Overall, I had a very pleasant month-long stay, and would stay here again if I return to Toronto :)
