All in all a very nice host and a really cool place to spend some time in Toronto. Would book again.
More detailed:
Sarah was very helpfull in every way. She helped me with my luggage before check-in, gave tips about Toronto as well as directions from her place. She was very kind and accommodating, and uncomplicated concerning check-in and check-out.
The place itself was clean and comfortable, and the view was spectacular. The place itself was quiet. Many landmarks were in walking distance and access to public transport (I.e. to both airports) was easy.
