Kathy, THANK YOU!
Tthe once famous Gellert has been a run down victim of communism since the end of WWII. Here is a little history: https://www.danubiushotels.com/budapest-guide/the-100-year-history-of-the-gellert-hotel-spa
But good news about the Gellet Hotel. A few years ago it was purchased by the Mandarin Oriental Hotel Group. These are they guys that run some of the finest 5 star hotels all over the world. The Gellert is closed now for renovations and is slated to reopen, fully renovated and upgraded in 2027. https://hungarytoday.hu/renovation-of-budapests-hotel-gellert-starts-to-restore-it-to-its-former-glory/ and https://edition.cnn.com/travel/hotel-gellert-restoration-budapest-hungary
The bath house remains open. https://www.hasta-standrews.com/features/2023/3/5/soaking-in-history-the-gellert-baths-of-budapest
But having stayed there you stayed in great history and in the footsteps of great (or at least interesting) individuals. From one of the links above:
"The virtuoso violinist Yehudi Menuhin was the first famous hotel guest after the war, and enjoyed the Gellért’s hospitality on a number of occasions. Statesmen such as Richard Nixon, the Austrian chancellors Julius Raab and Bruno Kreisky, the Iranian shah Pachlavi and his family, the Dalai Lama, the Vatican Cardinal Secretary of State Agostino Casarolli, Nobel Prize-winning physicist Werner Heisenberg, American medical researcher Albert Sabin, the world-famous actors Kirk Douglas, Antony Quinn, Marina Vlady, Alberto Sordi and Jean Fonda, the cellist Pablo Casals, the violinist Isaac Stern and pianist Arthur Rubinstein, the conductors Carlo Zecchi, Gábor Carelli and Roberto Benzi, the violinists Igor and David Ojsztrah, the operatic tenor Giuseppe Di Stefano, the Soviet film director Grigory Naumovich Chukhray, composer Dmitri Shostakovich, and, more recently, Andrew Lloyd Webber and Hungary’s own Oscar-winning cinematographer Vilmost Zsigmond have all stayed at the Gellért."
Oh and I read in a biography of Oscar Schindler that he stayed in the Gellert when he came to Budapest to try and warn the Jewish population.
