Ok, first of all the place itself. I don't think you could land in a better spot in Toronto, honestly. The Kensington Market area is the most distinctive part of the city; basically it's exactly what you're looking for as a traveler, and Andrew and Elizabeth are right there, on the border between Kensington Market and Chinatown (which is also pretty cool). So, the location is excellent. The room itself is nice, comfortable and clean, along with the rest of the apartment.
Second, Andrew and Elizabeth, your hosts. In a (hyphenated) word, they are super-great. Very well-informed about the city, yeah for sure, but also they were above-and-beyond in terms of hospitality and general helpfulness, nonpareil as hosts. And, just good people, honestly. When you land as a newbie in a foreign city, staying with people who are nice and who you can trust, just makes everything way better. Andrew and Elizabeth grade out as A double-plus.
