to be honest, never in my life heard about those 2 places, so i asked my grandfather. He told me that Villa Riachuelo and Villa Real do exist, and they changed their names like 2 decades ago. Riachuelo is now Lugano and Villa Real is now part of Versailles.
the travel distance from those places is preetty sshort because there is a major freeway that runs from Nunez to Villa Riachuelo and from there to Boca. (30 mins by car @ 120 km/h.)
thank you bruce, now i know more about my city!
