In the last days of March, Roger Boniche attended an extraordinary event in Cuba. The Rolling Stones, one of the most influential bands in the history of Rock, offered a concert in Havana on the heels of President Barack Obama’s visit. The 40-year-old orthodontist didn’t want to miss this event, so he flew to the island to witness it first-hand. While he was enjoying the music of the British rockers, he earned money by renting out his house through AirBnB. He posted an ad on the site, and the company did the rest for him.
