Bob and Yara's place is absolutely adorable, the location is fantastic (the restaurants on Ossington are INCREDIBLE, and transportation downtown is a breeze), and they were extremely responsive and helpful hosts. I stayed for five weeks while I was in town for work, and it was fantastic.
There are some small things that might stop some people from enjoying themselves, all having to do with it being a basement apartment. The ceilings are low, there isn't much natural light, and you can occasionally hear footsteps or conversations from the house above. But those are things you just have to expect when you're staying in a basement, and they're so minor compared to the enormous value of this place (the price is amazing!). I would happily stay again!
