I just moved to Toronto from Europe, and I lived with Andrew and Elizabeth for my first month here.
They are really nice people, and helped me out a lot. I really enjoyed my time with them, they are well travelled and we always had something to talk about. The location is really good, I usually just walked when I went somewhere. (Kensington market,Downtown, CN tower, museums)
MeowMeow, the cat is really cute, but somewhat shy, but she will open up when she starts to get used to you.
I definitely recommend the place, but I would stay at least 2 weeks or more, because there are so many things to see in walking distance.
