Airbnb was quick to open its doors to Cuba once the country enjoyed warmer relations with the US, but there was a big gotcha: you could only book a stay if you were a US traveler. That ruled out... well, most visitors to Cuba at the time. Today, though, it's a different story. In sync with President Obama's trip to the island nation, Airbnb has received a special exception that lets its Cuban hosts accommodate anyone, whether they're locals or Canadians on snowbird vacations. The expanded service starts April 2nd, or a year to the day when the company first set foot in Cuba.
