We spend one night at Katyas apartment. The Check-in procedure was flexible and easy. The apartment was clean. If you are staying longer there keep in mind that the the doors and ceilings are quite low. For us just staying the night it wasn't a problem. The apartment is an quite suburban area with a 10 minute walk to the metro station. So you might be in downtown Toronto within 30 minutes.
All in all we had a good time and I'd recommend Katya as a host!
