Here is an attempt to suggest few travel tips, guidelines. If you happen to be at Piraeus’s tourist location for the first time, the language problem is bound to be there. Most of the information available in the city or over the internet is gloomily not in English.
Monastiraki metro stop:
From Athens, the cheapest way to get to Piraeus is by the readily available metro. Monastiraki metro stop is the best option where you don’t have to change trains.
Other stations direct to Piraeus are ‘Tission’ & ‘Omonia’. You can also take the ‘Syntagma station’, the new & beautiful metro spot with a transfer in Monastiraki that will drop you right in front of the Piraeus Central Port.
Express bus, Trolleys:
One can also avail of the express bus facility & trolleys from Athens international airport, where an excellent network from E96 connects the airport with the port of Piraeus, metro line 1.
Bus and trolley tickets can be purchased at booths and kiosks near the bus stops. The ticket prices are sensibly charged.
You can validate your ticket by asserting it into one of the meters that will get punched.
Be cautious & keep the ticket until you leave the bus since it’s not uncommon to have a ticket-checker check their validity. If you are found that you haven’t punched your tickets, then chances of penalty/fine can’t be avoided that might require you to pay a few euros. So, better to prevent embarrassment by following the correct procedures.
DO NOT validate your 24-hour ticket more than once.
