The location near the Reeperbahn and the harbor, the clever use of space and light, and a cool bar that attracts thousands every weekend make the Empire a favorite. The white-walled guest rooms feel spacious and airy, and most have river views. Dark-wood banquettes replace traditional desks, and pocket doors allow entry into the bright bathrooms. Even though the hotel is three short blocks from the center of the Reeperbahn, there is little noise. You cannot even hear the revelers who line up to sip expensive cocktails in the 20 Up bar, which sits on the hotel's top level and has awesome views of the Elbe and Hamburg. On Saturday night, the line for the popular bar snakes through the lobby. After 5 pm, a sushi bar opens in David's bar on the ground floor.
