Remember growing up and seeing how big the Fresh Prince of Bel-Air mansion was? I always wondered what it would be like to live in that thing. What about you? Yes? Good thing, starting September 29th you can rent the mansion through Airbnb. The rental will only be available for 5 one night stays. However, right now on Airbnb, the cost is only $30 a night. You read that right. Your dream of staying in the Fresh Prince of Bel-Air mansion is only $30 out of your pocket. Here's the bad news: there are only 5 nights available, so make sure to log onto Airbnb first thing to snag your night's stay.
