Athens

Glyfada bay area where all bars are in line. And in the center Kolonaki area!! All are open til very late. And of course the bars close to Klathmonos square like the Clumsies etc. The latter try it for sure

I suggest akti vouliagmeni, or yabanaki which are organized beaches with an entrance fee.

Sure, where are you staying and how do you commute?

Hi Asad!! It depends on what you want exactly? You prefer Athens, islands, seaside? You need to further clarify. And I guess you are referring yo Greece solely.
