Madrid’s Best Luxury Hotels Were Once Actual Palaces

"In a palatial-style early 20th-century bourgeois building, this One MICHELIN Key stay blends a fresh, natural approach to luxury with historic elegance by preserving a spectacular elevator, a marble staircase, restored stained-glass windows, classic corner turrets, angled façades, and balconies; expect 78 tastefully elegant rooms, a fine-wood-paneled lobby where live piano plays each afternoon, the chance to enjoy classic British High Tea, a perch at the crossroads of Chamberí, Tribunal, and Chueca, plus the iconic Invernadero’s excellent brunch with live harp music and a spa Sleep Ritual designed to help you rest like royalty." - The MICHELIN Guide
