For the most part, we loved this Airbnb! It's a bit smaller than we thought from the pictures, but for the value, it was great. There were four of us: me, my wife, our 6yo son, and his infant brother. Being so close to the subway was fantastic, and there are a few great places right in the neighborhood that are solid for coffee, food etc.
We had only two complaints:
1) There was nowhere to put our clothes. The lone closet had items stored in it, and apart from a tiny cubby next to the bed, there were no shelves anywhere to lay out our stuff. A dresser somewhere or at least shelves in the closet would really improve things.
2) Our biggest issue was that on two separate occasions, groups of people hung out on the front steps of the building right in front of our window, smoking and drinking and talking—LOUDLY—late into the evening. It must happen frequently because there is a sign specifically asking folks not to do that.... which was ignored by these groups.
In general we didn't mind the average street noise /traffic coming in (we live in NYC), but the groups of people were literally ten feet from our bed. Similarly, another tenant in the building came home at 1:30am one night (granted, it was a Saturday night), and his/her entrance woke us all up up. The Airbnb unit shares an interior hallway with the other apartment in the building, and the door to that hallway doesn't mask noise at all.
In short, if you are NOT a night owl, this apartment may not be your best fit. We wouldn't choose it again, but if you are planning to visit Toronto and be out into the wee hours, you'll love it.
