The stately late 19th-century buildings at Rosa-Luxemburg-Strasse 11-13 were originally used to house German officers, and they’ve served various functions since, notably as a military hospital during World War I and later as a Cold War–era KGB surveillance station. Today, this restored landmark is home to the stylish Lux Eleven Berlin-Mitte. Rooms blend old-world character and modern design. All feature open floor plans with sleek workspaces, exposed stone details, custom lighting, and double-glazed windows with floor-to-ceiling blackout curtains. Some face views of Alexanderplatz and the nearby TV Tower. Larger suites have courtyard-facing balconies, while the penthouse suite has two bedrooms, two bathrooms, a cozy living room with an emerald-green velvet sectional sofa, and a private terrace. All rooms have kitchenettes with full-sized refrigerators, and while the concept is more “serviced apartments” than high-touch hotel, Lux Eleven does feature a restaurant and bar, Luzii, as well as the more casual Luzii Café & Deli.
