We really loved Colleen's place. It's located outside of downtown Toronto, approx 10min walk to nearest subway station and approx 10min subway ride (with 1 change) into downtown. We really enjoyed the location was we got to see other places outside of downtown, and Leslieville is a really nice town.
5* for cleanliness, amenities and facilities. Kitchen is fully kitted out, bedding is comfortable and plentiful.
Some building/pipe noises may disturb light sleepers but it didn't affect us too much. There are some steep stairs at the entrance so perhaps not advisable for those with mobility issues or prams/buggies, however we had 2 large suitcases and managed just fine.
Would highly recommend this stay and we'd definitely stay again.
