Matt's place is an awesome older home that he's beautifully renovated. It's in a residential Toronto neighborhood, close to downtown but very quiet and with great local character.
This was our first time in Toronto and we found the location to be ideal. Many terrific restaurants are in easy walking distance, and to explore further, there are streetcars very close by. We saw a Blue Jays game and the stadium was easy to get to by public transit. Here's a tip if you're visiting on a weekend: the 1-day unlimited transit pass, normally $12.50 per person, is good for a whole family on weekends and holidays. Toronto has a great public transit system and that's how we got around during our stay.
(The private off-street parking was a great bonus and it's plenty convenient to come and go by car, with easy in & out, but we found driving in the city to be unnecessary so we left it parked for the duration of our stay.)
Matt's house is nicely outfitted, especially if you're traveling with children. There are lots of kid-friendly features, including games and toys to play with, and even a full-sized crib (with clean bedding) tucked away in the master bedroom. Our kids are 6 and 9 so not crib age anymore, but they definitely enjoyed the games. If you're traveling without children, the kid stuff is unobtrusive and you probably won't even notice it.
We had such a great time in Toronto that we would love to visit again, and would certainly come back to Matt's place!
