The hotel is a perfect replica of an architectural creation by the great Friedrich Stowasser commonly known as Hundertwasser. Friedensreich Regentag Dunkelbunt Hundertwasser (born Friedrich Stowasser, December 15, 1928 – February 19, 2000) was an Austrian painter and sculptor. By the end of the 20th century, he was arguably the best-known contemporary Austrian artist, though he was always controversial.
