We stayed here for 2 weeks after we had just moved to Toronto. The bedroom was very spacious, and the living/dining was a fine size, although the kitchen was tiny with very little bench space. Comfortable big bed, pay TV, iron, lots of linens, all the kitchen tools you could need were all supplied. Our only real gripe was that the place wasn't properly cleaned - a maid came in once a week but she didn't actually vacuum (only sweep), and as a result the floor was constantly covered in dust (I think maybe the heating vent was blowing dirt in?) 247 security, which was great. It's also very quiet - we never heard a peep from anyone! The gym was very basic (two treadmills, a few weights), but fine.
The location is FANTASTIC - around the corner from College subway station, across the road from pharmacy, Starbucks, mini-mart, food places, etc. Short walk to the Eaton Centre. Definitely good for long-term rentals, but I'd probably want to stay somewhere a bit nicer if you're in Toronto for a holiday (the building is fine, just a little dated).
