Me and my boyfriend stayed at Kent's place a little over a month to finish of my time in Toronto. It was a good distance to commute to the University and decent time to go downtown. Since we were the first to live in the basement there were a few little things missing in the beginning, but Kent always responded very fast to give us what we needed.
Other than that there's definitely enough space for one person, with two people it can get a little bit crowded. And on a side note, since the apartment is in the basement and close to other houses, there isn't a lot of daylight coming in through the windows, though it never bothered us too much since we were gone most of the day.
Overall we enjoyed our time there and I would recommend it if you want a private place in Toronto in a decent distance to downtown.
