Madrid’s Best Luxury Hotels Were Once Actual Palaces

"Tucked into quiet Chamberí in a French-style neoclassical mansion built in 1895, this One MICHELIN Key, intimate and storied refuge — still owned by the descendants of the Duke of Santo Mauro — channels 19th-century aristocratic Madrid with Persian rugs over hardwood floors and individually styled suites across three grand buildings; what sets it apart are the truly personalized attention to every request, an extraordinary garden created in honor of the Duchess and her love of century-old chestnut trees, the daily Casilda cocktail crafted with chestnuts and served each afternoon, and ever-present fresh flowers in prized oriental porcelain vases." - The MICHELIN Guide
