We had a great stay at Amit's place. Like others have written, you really cannot beat the location - it was fantastic. Amit did a great job of keeping in touch and answering any questions we had, both in the lead up to our stay and during our stay. This was my first time using airBNB so we had some questions leading up to the trip and he graciously answered them all.
My only (minor) complaint was that the building hadn't turned on the AC yet and we had a couple warm days when we were there, so the unit got a little warm during our stay. Saying that, Amit did what he could when we asked him about it, and it was nothing that cracking the windows a little bit didn't fix.
All in all a great stay! Would definitely stay again next time we're in Toronto.
