I liked staying at Amy and Graeme's so much that I decided to stay there for the whole three months that I was in Toronto. Amy and Graeme are wonderful people who made me feel very much at home.
There are three guest rooms in the house. When the rooms are rented to couples it can get a little crowded in the kitchen and you may have to wait for a bathroom. That did not happen a lot though. In general the sharing of the facilities worked out just fine.
The neighbourhood is great, everything you can think of is in the vicinity. With a bike it is even better, you are downtown in no time. And Amy and Graeme know all the good places to go to.
