Our 4-day stay was mostly pleasant except for the one night when the host (who lives on the upper floors of the home) held a very loud party that lasted until 3am. Also, the bedroom is located near a water line in the basement so you can hear the constant flow of water which can be an issue if you're a light sleeper.
On a positive note the place is clean and in a charming neighborhood if you want to avoid staying in the center of Toronto's hustle and bustle.
