Overall Impressions:
I stayed at Katya's for 4 nights. The apartment was clean, quiet, and matched the pictures exactly. It would be difficult to find a nicer / closer AirBnB for the price of Katya's.
Apartment:
The apartment comes with a queen bed (which was quite comfortable). There is also a desk and dresser, which were greatly appreciated. The temperature and light in the unit made for a comfortable night's sleep. A dehumidifier in the bathroom keeps the humidity down, which is great for hot days in the summer. Being a basement unit, there were occasional noises from upstairs, but nothing excessive or bothersome. I noticed that some parts of the basement have low ceilings (particularly the stairs and one area of the bathroom). I'm 5' 10" and didn't have any difficulties with regards to height. However, I imagine the height could be a minor inconvenience for anyone over 6' 2".
Privacy:
One of the things I appreciated most was privacy. The apartment has a separate entrance around the side of the house with a key lock. The bedroom in the basement also has a door with a key lock. There is shared laundry in the kitchen area but it was never used during my stay. My interactions with the host (Katya) were limited to check-in and check-out, so it felt like I had the unit completely to myself.
Transportation:
I commuted via subway to/from the financial district in downtown Toronto for work each day. I was able to get downtown within 30–40 minutes of leaving the apartment (10 minute walk to the subway + 20–30 minute subway ride). If you have a vehicle / plan on driving, parking was available on a nearby street. I was able to find a parking spot that was just around the corner from the apartment.
