Recoletos sets the price ceiling for residential Madrid. The strip between Retiro park on the east and the Paseo de la Castellana on the west — running from Puerta de Alcalá up to Colón — is where old money, private banking, and international luxury retail have compounded for over a century. Park views on one side, embassy row on the other, a ten-minute walk to the Prado. What you pay for is the address: access to a civic and cultural geography that no other part of Madrid replicates, in classical buildings that cannot be built again.
