Serguei's place is on the 7th floor of a tall condo, not far from Royal York Rd near the Gardiner. The unit is a complete one-bedroom condo decently furnished.
I had a nice quiet stay, the huge bed in the bedroom is comfy as can be, the unit has a clothes washer and dryer which is good if you are staying for a bit. Getting in and out of the garage is tricky (huge underground maze) but after a couple of entries, you get the hang of it.
Although I did not meet Serguei, I did communicate through the AirBnB app and he always responded quickly.
I would stay again and I likely will.
