My colleague and I stayed at Bill's during our business trip to TIFF, and it was amazing! The place is cozy and clean, Bill and Cindy were always there for us and it felt just like home.
Location is great too, there are couple of supermarkets in the walking distance, as well as lots and lots of cafes, restaurants and bars. As for the transportation - we used taxi and it's 11-15 min ride to the main TIFF venues.
Overall, we highly recommend this place and we'll definitely book it again next year:)
Bill, Cindy, thank you for you kindness and hospitality!
