Christina's place was exactly as described, located on a quiet side street, with lots of room for a group or family. We were 5 friends in town for the marathon race weekend, and were pleasantly surprised to find such a nice place with the luxury of each of us having our own bed. The lock-box allowed us to come and go easily without having to coordinate for someone to be back at the unit to let us in or worry about a key. Christina was kind enough to let us check-out late after our race, allowing us to shower before the long drive back to Montreal.
The only thing to be aware of, and that is mentioned, is that there really is no insulation/sound proofing between the downstairs tenants and the unit. We ran into the tenant during the day, and he remarked that we had been up early that day (despite us being quiet while making our breakfasts). So just be aware that even regular noise levels can be heard in the basement unit, and vice-versa (we could hear the TV and conversation from the basement unit as well in the evenings). The tenant didn't seem to mind, telling us it wasn't our fault, but just something to be aware of, and Christina mentions this in the listing, when your reservation is confirmed, and again during messages prior to the check-in day, so not like it was a surprise. Just something to be conscious about during your stay.
Thanks for the amazing hospitality, Christina! We had a great time in Toronto!
