Lonely Planet
Concierge "Opened in 1685, when the Neustadt was rebuilt after a fire, the 26-room Rothenburger Hof has the traditional feel of a historical, family-run inn, but its wealth of amenities—including Turkish bath, gym, sauna, and swimming pool, as well as a lovely sunroom and terrace—also draws luxury-seeking travelers"
Lonely Planet "Let the events of the day float by while relaxing in the Moorish-style steam room or small pool"
