We are stopping in Athens again before leaving Greece. We have already spent a few days there and have visited enough ancient sites and museums. Have also walked all over Syndagma, Plaka, Akropoli and surrounding areas. Visited Kolonaki and randomly took the subway to a few stations(Attiki and another place) to see what was going on, but found only residential areas. Are there other neighborhoods of interest or should we think of some day trips to Glyfada or Sounion? Where do regular residents hang out in the city? Is there a business district?
