Has anyone had experience with the Piraeus - Athens X80 express bus to the Acropolis and Syntagma Square? What are the cost, hours/days of service, duration/frequency of trip, location of stops, etc.? The information at oasa.com is difficult to decipher; any help would be appreciated.
My experience with Greek buses is that you should figure them out locally as you go because online schedules are rare and/or hard to decipher. Athens Metro Line 1 also runs to Piraeus. According to p. 217 of Rick's Greece book, both the Metro and bus #040 run about every 10 minutes. I don't know whether bus #040 has been replaced by the bus X80 you were looking at.
I've never used it but it looks like this is a reasonable description.
Alan that's a GREAT link for people getting off CRUISE ships. SShaw, you did not say if you planned to arrive in Piraeus from a cruise or from a regular ferry (the piers for Cruise are over a mile away from the regular piers). If you come in on a regular ferry, and want to get to Syntagma Square,you should take the Green Line Metro, as others have said, to Monastiraki station. Then u will need to transfer to the Blue Line and go one stop, to Syntagma. This metro map (cllick to enlarge) makes it very clear http://www.ametro.gr/files/images/AttikoMetro_Athens_Map_eng_LG.jpg
Janet have given you very detailed information regarding the Metro.
It's very easy to travel by Metro to/from Piraeus to Athens.
Just be prepared to climb the stairs in the Metro stations, it's an inconvenience especially if traveling with heavy luggage!
My wife & I stayed at Nefeli hotel (healthy good start breakfast) a couple blocks from Syntagma Square Jan 5 - 8 2015. My wife has MS that will immobilize her in heartbeat. The buses were very easy to get around when complimented with short cabs as needed. At airport we bought a 72 hour all transport pass. Airport to Syntagma we took subway, it was ok at best, from Syntagma Square to airport we took XPRES bus, easier to get on as they line up & drop off along side the square. We took the #40 from the 1/2 block off Syntagma Square (in front of espresso café) to Piraeus for the Epiphany Celebrations (very cool). You can walk UP to the Acropolis, we took cab and were able to walk down and through the museum, then through the incredible old city shops to our hotel, my wife had 1 spell, but toughed it out all the way. Our trip included London, Istanbul (Turks hate Americans so be real careful, watch your 6), Barcelona (had my wallet stole at McDonalds, I think it was the counter girl), Paris, Caen (hired taxi for Normandy Beaches), Paris and Amsterdam.
There is some discussion of this on cruisecritic.Com in the ports of call section. Generally people have been happy with X80. Someone recently gave good directions from cruise terminal A and others have reported how to catch it from terminal B. You can buy the 4 euro 24 hour metro and bus ticket from a kiosk near the port.
Oh, have to go to forums or community section of cruise critic to find ports of call, Greece threads.
