Great location - 7 minute walk to Puerto del Sol, 10 minute walk to Prado, 15 minute walk to Retiro Park. Apartment was sparkling clean upon arrival. Sergio was very accommodating with an early check in and provided us a list of restaurants. Decent views from windows. It was a bit noisy at night with late-night revelers, so bring ear plugs if you are a light sleeper. Would definitely stay here again. Thanks for a great visit, Sergio!!
