Stopping off at a Hyatt hotel, you know what to expect: a consistently high standard in service, catering, and facilities. So what’s so special about this house at Potsdamer Platz? The secret lies, among other things, at a dizzy height, in Club Olympus Spa & Fitness on the 8th floor. A unique view above the roofs of Berlin is to be had here while swimming in the canopied pool or chilling on the 2,690 sq. ft. lawn on the rooftop terrace. Freshly recovered, you treat yourself to a tea in the lobby or a drink at Vox Bar, a popular meeting spot not only during events.
