I stayed for about 5 weeks.
The owner was extremely responsive and the check-in was easy. The place is in a great location and very clean.
Generally, I was happy at the place! The rooms and the house aren't necessarily cozy. It's all very pragmatic: There is a bed, a desk, one plate, one spoon, one fork, one towel and one cup provided for you. Frankly speaking, for a long-term stay it was by far the cheapest place in Toronto. So I'd still say the value-for-money is quite good!
For me the biggest draw back of the apartment was the noise level. It should be mentioned that the walls are quite thin. If the other people staying in the apartment tend to speak loudly or watch movies loudly you'll definitely hear them. This, however, isn't the owners fault but has more to do with the people staying there.
