Have you ever had a guest stay so long you thought to yourself, “I need to start charging them rent!”? I have to wonder if this is how the concept of Airbnb came about. Or maybe it all came from the movie called The Holiday with Kate Winslet and Cameron Diaz. In the 2006 movie, the two characters swapped houses for the same 2 weeks. I remember thinking what a great idea that was but wondering how you line up the switcharoo. Then enters Airbnb 2 years later in 2008!
