American hospitality giant Starwood began managing a hotel owned by the Cuban military on Tuesday, opening one of the biggest holes in the U.S. trade embargo on Cuba since Presidents Barack Obama and Raul Castro declared detente in December 2014.

The facade of the 186-room Quinta Avenida hotel in Havana’s upscale Miramar neighborhood has been emblazoned with the logo of Starwood’s Four Points by Sheraton business travel brand and travelers can now book rooms through Starwood’s website.
