I've been through that situation before, and without AirBnB being the culprit. In fact, it was how well my girlfriend and I had done up the place that the owners wanted to take up residence there.
I think my biggest peeve is the ease at which indiscriminatory lease is made to anonymous people for an unchallengeable fee, rendering buildings where security has been paid for open to anybody who's willing to put forward ~$50 - $100.
I've used AirBnB to visit Montreal and stayed in a couple's charming townhome and it was a great experience.
The two applications aren't equal in my eyes, so it seems there needs to be a line drawn -- the question where is a tough one. But that's me. There seems to be a wide range of opinion here.
Anyway friend, I'm all for regulations where fitting but there are no guarantees no matter what guards you put up that you won't hit a bad run, so it's not something I'm going to spend my time worrying about and instead prepare for whatever I can.
Anyway, you should, because it is driving up rents for you. And if the person renting to you decided they want to go the effort of making 2x as much money, they could kick you out and do it.
