The apartment is very clean and cozy, the beds are comfortable.
Denis is really friendly. He showed us around when we got there and gave us suggestions on where to go. He always reply you and easy to communicate with.
You can cook your own food and wash your clothes there.
The only thing you need to be care of is the hand wash sink in the bathroom. It's no big, so it's easy to splash the water out.
Overall it was a nice stay in Denis' apartment in Toronto.
