Yen is a great great host. She was always responsive and very accommodating. She even went te extra mile to send help for my girlfriend to move luggage upon check out while I was out of the city.
The place was clean, spacious, in an unbeatable location in downtown Toronto and had everything we needed.
There are only two issues: 1) it's quite noisy as the unit is right on top of a bar and given it's an old building noise does travel loud and clear especially during the weekends; 2) the stairs are steep and narrow which is mentioned in the descriptions of the house accurately and we booked the place knowing the issue exists, but do make sure you are comfortable with this part.
