Stayed at Reza's place for a month, it was what I expected it to be.
It's located in one of the most expensive neighbourhoods in Toronto, so you're mostly paying for the location. However, the basement itself isn't bad either. The only major issue that I noticed was the low ceiling heights. If you're taller than 185cm, you might hit your head when in the kitchen area due to the dropped ceiling above the stove and sink. I suggest that the host pad the ceilings with soft material to avoid injury.
Other than that, Reza himself was very accomodating. We needed wired internet connection, which he happily provided. The connection was Bell FTTH with fantastic quality. Communication was excellent and responses were quick. There was one queen bed in the bedroom and a comfortable convertible sofa bed in the living room. Parking was provided as described in the listing. Overall, it was a good stay. Thank you Reza.
