Sergio's flat is absolutely wonderful, light, warm and clean, and right in the heart of Madrid. It is very well set up for families or for a couple, and has excellent modern furniture, a great shower, and an elevator! The location could not be better, in calle Huertas, close to the Prado, the Puerta del Sol, and so many bars and restaurants, as well as having supermarkets nearby. Sergio was a great host and communication and assistance with any requirements was very fast. I would thoroughly recommend Sergio's place.
