Our first option in Toronto would be staying near downtown, but we found this gem in a beautiful surrounding, just 20 minutes by car to Old Toronto.
Victor and his children's house was very welcoming. He received us and gave all the instructions and later was available through cell. We got a well organized house, with comfortable beds, new sets of towels - not the old ones from somebody living there -, a well equipped kitchen, a good BBQ and a patio ... all you need to feel like a real Torontian.
Neighborhood is very charming. Nice houses, children playing at the street, a local park nearby. Much, much green everywhere.
Our family did enjoyed the time spent there. Would return to the same house a next time in Toronto. Just would recommend having a car- three is plenty of parking downtown and a app i.e. Parkopedia can show you the best places and rates. Besides that, Toronto doesn't have the same public transportation system as you find in European cities.
