 The interior decoration was equally lavish with marble covered walls and adornment by the Berlin-born artist Carl Langhammer (1868–1956).The Excelsior may not have been as distinguished as Berlin's Adlon, Kaiserhof or Esplanade but it was the largest, and at the end of the twenties it firmly established itself as the largest not only in Berlin, but across the whole continent.At the start of the 1930s NSDAP leadership in Munich earmarked the Excelsior as Hitler's base in Berlin until he secured leadership.
