We stayed at Susan's place for university check-in weekend and it was perfect for our needs. Big bedrooms, multiple bathrooms, and plenty of space when everyone needed their own space. Toronto in summer is hot and the a/c kept the house cool and comfortable.
The location in the High Park/Roncy neighborhood also fit our needs, with just a short ride from the airport and easy access to downtown Toronto via streetcar. The Roncesvalles district with its shops and restaurants will keep you well fed and entertained during your stay.
Susan is a great host who communicated frequently and responded quickly to any questions. We will definitely stay with her again.
