Hotel amenties and information

Hotel Description

With the second largest Baroque castle in Europe and the Art Nouveau complex at the water tower, it is no coincidence that in the niu Square you will discover historical anecdotes from the Baroque period. Opulent stucco elements and sumptuous chandeliers provide a princely touch. But the niu Square remains innovative and unique, because the design is urban-modern, surprising and shines with extraordinary details. Whether ox breast, plum cake or original Mannheim spaghetti ice cream – there are plenty of Mannheim specialities in terms of culinary delights. With our technical equipment, we leave the Baroque period far behind in the niu Square. Available anywhere, anytime with ultra-fast WIFI, USB ports, built-in power supply and cool background music.
