Al Habtoor Palace, Budapest

What the classifiers highlight

Built between 1914 and 1918 as the Adria Insurance headquarters, the building later served as a Ritz-Carlton before this conversion. Original stained-glass cupolas and wrought-iron sunflowers survive, paired with 170 rooms and 29 suites that Forbes notes for soundproofing despite the downtown address. Upper floors look over St. Stephen's Basilica and the Parliament building.
