Hotel Nassauer Hof
Situated opposite the Kurhaus, this has been Wiesbaden's premier address for well over a century and was the first hotel in Germany to be awarded five stars. Previous guests have included Dostoyevsky, John F. Kennedy, Audrey Hepburn, and the Dalai Lama. Unsurprisingly, the rooms and suites provide quintessential luxury; all are quiet, comfortable, classically furnished, and have modern bathrooms. The hotel is home to three restaurants, including Wiesbaden's only Michelin-starred restaurant, Ente, and the gorgeous Orangerie (where breakfast is served). There's also a luxurious spa and beauty treatment space, including a remarkable rooftop thermal pool with city views.
