"Throughout Budapest are a whopping 123 therapeutic hot springs, but these, in the stately, slightly dusty Hotel Gellért (built in 1918) might be the most famous. The communal bath in the center of the hotel spa is for everyone, but the most interesting traditional spa experience is in the back thermal pools, which have been coed since 2013. Here, join Hungarian locals in pools of varied temperatures, steam baths, and saunas, and jumping into ice-cold baths in between. Everyone takes their time to not only bask in the baths but also gaze at the Art Nouveau tiling on the walls and vaulted ceilings."
