We really enjoyed our stay. Yani was a communicative and flexible host who obviously wanted to take care of us. We had just about everything we needed, and Yani was responsive to any requests we had. There were lots of clean linen and towels and the kitchen was well stocked (though some of the modern devices were a bit tricky to operate). Location is really ideal for being close to transit, shops, restaurants, nightlife, etc. and the free parking space was an added bonus. The bedrooms and house in general were incredibly quiet - particularly impressive given this location's proximity to such a busy area of town!
In terms of accessibility: as the listing and other reviewers have noted, there are three flights of stairs (with no handrails) and there is a high in-step into the bathtub/shower, so this is not really an AirBnB for those with any kind of mobility issues.
Overall, a pleasant, quiet, and comfortable location with almost all amenities you could need for a fun group stay in Toronto!
