I've had fine experiences with Airbnb overall. Did have one host that wanted a copy of my driver's license and I politely said I wouldn't be doing that, and then a few weeks later he canceled my reservation at the last minute. Airbnb did reimburse me and I see he is no longer renting there.

Mostly it's just staying in a house and the rare times I've met the hosts they've been nice normal people. YMMV of course but that's true of hotels as well.
