Had a very pleasant stay here for 2 weeks as a early fall trip! Location is fantastic! Subway (TTC) station is just right down the street. If you don't mind walking during summer/fall time, many major touring sites are within walkable distance. The city also has a great bike lane system and there are two biking docks around the apartment. Big grocery shops and pharmacy also just next to the building with less than 2 mins walk.
The apartment unit is in the high up building, which may not be as fancy as the new buildings around downtown area but it's pretty clean and with great view in the balcony. 5 elevators, trash tunnel, washer room in B1 (may need to buy a laundry card). The unit has all necessities prepared that really makes my stay a lot easier and comfortable! I also did remote-working from the unit and had no issues with the wifi/internet. The host, Dan, communicated pretty well on the check in/out details and responded efficiently.
Overall a great stay and enjoyed the trip in the city of Toronto. Will definitely want to come back again next time in Toronto!
