I love Airbnb - simple, straightforward and easy to use. Their app on the iPad needs some work though, but other than that their design is quite simple and easy to follow. Their customer support is awesome - the other day I had asked my renter to check if there was a key and she didn't find any. A few weeks later, when she found it, airbnb immediately reached out to me to let me know something was up.
