Entire apartment in central location; 5 mins walk to Retiro Park, Atocha station and museums.
Unlike most of apartments in central Madrid, this one is very spacious. Two mezzanines opening to the living space were converted into bedrooms. Proper kitchen.
The apartment has two entrances: one via the main building entrance, up and down a couple of flights of stairs and through an internal courtyard, and a second, somewhat tricky, through a small door directly to the street.
