I was in Toronto for a conference and my stay at Samira's house was fantastic.
The house is relatively far from downtown but very well connected (on the other hand is very close to the airport) and there are several shops and stores in close proximity (including a 24/h supermarket).
The rooms and common spaces are very functional and well organized.
Samira and her family are always helpful with info and tips (one for all: the 10km running trail starting just behind the house), and Samira's husband also took me to the airport the day I left.
If and when I'll come back to Toronto I'll definitely check them again!
