I'm going to be getting to Athens on May 17th, staying in Piraeus, and then leaving early May 18th for a ferry to Mykonos.
If I order tickets online with blue star ferries, I still have to physically pick them up somewhere.
the problem is,I don't know which agency to pick it up from.
The main blue star ferry agency is at: ATTICA PREMIUM 26, Akti Possidonos, 185 31 Piraeus
Another is at : GIOVANTI 6, Aristidou Str., 185 31 Piraeus
Which one is cloest to the boat where the ferry to mykonos leaves?
