There's also a hostel on Clarence Sq., just south of King St. W, near Spadina (Clarence Castle). It's near the Global Village hostel on King & Spadina, but on a quieter street.
Check out Casa Loma, a soccer game (if you can get tickets) at BMO field, St. Lawrence Market on the weekends for the farmer's market, antiques market and fresh food, Kensington Market for a hippie vibe, coffee, and empanadas, and Spadina for Chinese and Vietnamese food. Hit up the Beaches Jazz fest on Queen St. East. It's an easy ride from Leslie Spit.
