Rome Cavalieri, Rome, Italy

Of all the cities in the world where one might expect to find hotels overflowing with great art, Rome tops the list—and the Rome Cavalieri doesn’t disappoint. The hotel has an art collection numbering more than 1,000 pieces from the 16th to the 20th century. Highlights include a crib that Napolean commissioned for his baby son; famous Beauvais tapestries in the lobby—the only public display of its kind outside The Metropolitan Museum of Art in New York and The Getty in Los Angeles; Andy Warhol’s famous Dollar Signs; and a series of paintings from the revered 18th-century Italian painter Giovanni Battista Tiepolo, which the hotel acquired in 2006. An on-staff art historian is available to give guests tours of the collection, and we recommend taking one. Via Alberto Cadlolo 101; 39-06/3509-1; romecavalieri.com.
