I read through other reviews and I think they were really accurate. Yes, it is a basement apartment, so low ceilings, definitely a consideration if you're tall.
The place was very clean, except there was some mildew around the grout in the shower at the seams (not surprising in basement shower, probably just needs to be re- grouted). The floor of the shower was spotless though, which is the most important thing since that's where your feet touch. The rest of the home was spotless.
The location is awesome - right off Bloor but not noisy, except for the subway which is a low rumble. You do not hear the traffic and street noise from Bloor at all. You could sometimes hear the people who live in the residence above but I'm not sure where you could stay in a big city like Toronto and not hear people around you!
Youquan communicates well and is quick to answer any questions. I actually had a last minute shift of my dates and Youquan was super kind to let me modify my reservation.
