Had a pretty good stay at Jj's place while in Toronto. The room is pretty spacious, with a nice comfortable bed. As specified in the description, noise does leak into the room from the window facing the street. So if you're sensitive to noise, it might be a good idea to invest in some earplugs or headphones.
The place is like a mini-hotel: there are numerous tenants in the place (3+). I never had any issues: there's two shared bathrooms, and never had to wait once for one to be available. There are locks on each bedroom, which is great for security. The location is good (in downtown) but is 10-15 minutes away walking distance from any subway station. As a result, I ended up using taxi-like services for my travel needs instead.
Jj is a great host and maintains the place well by coming by each day to clean the place up, etc. He was also very helpful in recommendations, etc. I should also mention that he was very flexible with the check-in and I was able to arrive earlier than the usual time with no problems, etc (YMMV on this).
I would recommend Jj's place to future guests, and would definitely consider staying here again.
