1908 mansion opposite the Retiro park. The classic exterior contrasts with the avant-garde interior decor, with its minimalist touches in line with other hotels in the AC chain. Some of the building's original elements have been conserved: the coffering, Talavera ceramic skirting boards, stained glass, wrought iron lamps, frescoes, the old wrought iron elevator and the mahogany book shelves. Sobriety and technology is demonstrated in the fitness centre, spa, plasma screens,wi-fi and avant-garde art. Creative cuisine at the Indice restaurant and lobby bar.
