Introduction AirBnB is a marketplace for short term rentals that allows you to list part or all of your living space for others to rent. You can rent everything from a room in an apartment to your entire house on AirBnB. Because most of the listings are on a short-term basis, AirBnB has grown to become a popular alternative to hotels. The company itself has grown from it’s founding in 2008 to a 30 billion dollar valuation in 2016 and is currently worth more than any hotel chain in the world.
