The Principal Madrid is a five-star boutique hotel housed in one of the most spectacular buildings at the start of Madrid's iconic Gran Vía — a magnificent early-20th-century edifice completed in 1917 and listed as a historic building by the City of Madrid. Reimagined by Único Hotels and a member of Small Luxury Hotels of the World, the hotel was awarded 2 Michelin Keys for its exceptional guest experience. Its prime location places guests within walking distance of Puerta del Sol, the Círculo de Bellas Artes, Cibeles Fountain, and the art triangle of the Prado, Thyssen and Reina Sofía museums.

The 77 soundproofed rooms and suites feature views of Gran Vía and the city, and are elegantly appointed with Nespresso machines, minibars, flat-screen TVs and luxury bathrooms. On the 6th floor, Ático Restaurante serves authentic seasonal Spanish cuisine, while La Pérgola terrace offers tapas, cocktails and sweeping Madrid skyline views. A 7th-floor solarium with sun loungers and a relaxation lounge with sauna complete the wellness offer. Versatile meeting rooms and private event terraces round out the facilities.
