The Westin Palace, Madrid, Madrid, Spain
Steeped in history, and a Site of Cultural Interest, this grande dame of Madrid is brilliant for exploring the Spanish capital. It's also a big draw for foodies, who come to enjoy memorable meals beneath La Rotunda's gorgeous Belle Époque stained-glass dome (its Sunday Opera brunch is one of the city's best), Asia Gallery's gourmet oriental delights, or the Green T Sushi Bar's fusion of Japanese sushi and Spanish tapas.
