Close to Recoleta and San Nicolas Districts. Its limits are outlined by Montevideo and Uruguay Streets, Cordoba and Eduardo Madero Avenues, San Martin, Corbeta Uruguay, Antepuerto Avenue, a street with no official name, and its imaginary extension up to Montevideo St.

Thousands and thousands of people arrive at and leave from Retiro, since it is the head station of three railway lines, the Bus Terminal and many bus lines. This is the crowded area in Retiro, that becomes a "Persian market" during rush hour. The elegant and refined area of Plaza Carlos Pellegrini, surrounded by luxurious hotels, large apartments and condos. The fine and majestic zone of palaces (Chancellery, Military Circle) on Plaza San Martín, and a clear and tough contrast almost invisible to the eyes of tourists: the slums located under 9 de Julio Highway.
