Airbnb has taken the world by storm. While the original idea for the service may have been renting out an extra room or second property, it's grown so large that now people even rent out the only residence they have. So, if you're a host and someone is staying in your home, where do you go? You now go to "Can I Stay with You While I Rent my Place on Airbnb?", or, as it's been dubbed, the "Airbnb for Airbnb."
