I stayed for one night since I was in Toronto for a 2-day workshop. The stay was nice, the room was fine with it being well air-conditioned and provided with the basic amenities. Despite being on the second floor, my room was well-isolated from outside sounds. The bed was near, clean and comfy for the sleep in. The prices are what they are and since TIFF is also occurring, I expected that. I chose the option which included breakfast and was pleased with both the breakfast staff and then breakfast selection. They offer to make omelette for you and you have a variety of other food stuffs to choose from.
My only qualm is that the hotel is far from downtown. Sure, it's off the TTC metro line (once your traverse the behemoth of a mall), but it still takes your approx. 40 mins from hotel to union station (barring any random TTC metro stoppages).
I would stay again however, being that far away from Toronto Downtown, you should prepare beforehand for the time loss of 1.5 hours back and forth.
