Marriott International Inc. said it will upgrade the Sheraton Frankfurt Airport Hotel & Conference Center at the Frankfurt airport in Germany.

The existing hotel covers three interconnected buildings with 1,008 rooms. It will be divided to allow for a 779-room Sheraton hotel and a new 233-room Marriott hotel.

The final stage of the renovation will start with the refurbishment of the Sheraton lobby, Sheraton conference center and shared dining facilities.

The 4,148-square-meter conference center will benefit from additional improvements over the next two years. The property is set to be fully renovated by the end of 2022.
