We stayed at Katy's at the start of our trip and it was a brilliant introduction to Toronto, being so close to Union Station, CN tower etc.
The check in was good, we were met by James who explained how the doors worked etc. and communication with Katy was good before and during our stay also.
The apartment was clean and tidy with gorgeous views over the harbour, and they had a pack and play for the baby which was great.
I would definitely look to book Katy's apartment again should we return to Toronto.
