I saw somewhere, and just cannot remember where, about the possibility of walking from a cruise ship to a metro station, and travelling by metro to the Acropolis. Is this possible? If so, could someone please tell me the name of the metro stations at Piraeus and the Acropolis, and can I presume that there will be some signage in English? Will be there on Tuesday 1st October. Would be grateful for any information, thank you.
