We highly recommend Tracy's well-located basement studio, and Tracy and her family as hosts.
As we were traveling with a recently-mobile baby, we really appreciated the ways Tracy set up the studio to accommodate a toddler: it was a huge help to find a range of books and toys, good quality high chair and cot, baby crockery and cutlery, and even a shelf in the fridge with a few yogurts and baby snacks (as well as a thoughtful range of staples and treats for adults). The open-plan studio is spacious and well-furnished, with good appliances in the kitchen and great bathroom fittings. It feels like part of a family home---but with entry by a side door using a key code, you needn't feel like you're intruding or don't have your own privacy.
The location is a charming suburban street directly adjacent the shops and facilities of Bloor Street West: a handful of groceries and restaurants are within just a few minutes walk. Two subway stops are very close by, providing easy access to downtown.
