Four Seasons Gresham Palace

The Gresham Palace is the finest Art Nouveau building in Budapest — and in a city where Art Nouveau is practically a religion, that's a serious claim. Built in 1906 as the headquarters of the Gresham Life Assurance Company, the building sat neglected through the Communist era before Four Seasons restored it in 2004 with a reverence for the original craftsmanship that borders on devotion. The iron Peacock Gates, the Zsolnay tile mosaics, and the soaring atrium are all original. 179 rooms and what many consider the single finest view in Central European hospitality.
