If you're looking for a peaceful place to retreat during your stay in Toronto, I'd highly recommend Ruth's place. It is perfectly located on a quiet residential street, yet still close by to a number of shops and restaurants. (I'd suggest Shinobu for authentic Japanese, Modo Mio Bistro for casual Italian and The Abbot for British pub fare - all just a short walk away.) Ruth keeps her home spotless, so cleanliness is not an issue at all. And she has great recommendations for lectures happening around town. I stayed here for a month and wouldn't hesitate to stay with her again next time I'm in Toronto.
