Opened in 2013 in a 100-year-old former bank building, the Park Hyatt has utilized the space well, with a restaurant in the former cashier’s hall and a pool in the former vault. The suites are spacious, and all rooms have more than just the basic requirements for your average traveler, including safes large enough for laptops. While the marvelous Grand Salon is typically used for banquets and business meetings, guests should definitely try and take a peek at this beautifully designed room. The prime location in the historic Innere Stadt, or first district, means most major sights are within walking distance.
