I've used Airbnb many times while traveling abroad, one of which I've even documented on this blog. I don't require much of where I stay: just a place to sleep, shower, and where I can keep my belongings while out and about. I prefer my host to be helpful, but not overbearing. And now I need to add, I'd also prefer my host not to be a nitpick - because if you're a nitpick, then you probably shouldn't even be a host.
