In the leafy Calle de Claudio Coello, in Madrid’s chic Salamanca District, is Hotel Único, one of the capital’s most iconic and sought-after boutique properties. Once a noble private mansion, Hotel Único epitomises the understated elegance of this 19th residential neighbourhood, originally built with the help of the 1st Marquess of Salamanca. The guest rooms have recently been beautifully remodelled by designer Maria Santos. This is the capital’s most upscale and desirable area, where the streets are lined with elegant boutiques, designer stores, galleries, and the most fashionable places to eat and drink. The perfect location for an elegant stay in the city.
