Bus Terminus B off Liossion Street, Athens

• Express bus E93 direct from outside the airport building to the bus stop at Liossion Street
• Yellow taxi direct from outside the airport building to the bus station
• Express bus E95 to Syntagma Square in Athens and then by yellow taxi to the bus station
• Metro from the airport to Monastiraki station and then by yellow taxi to the bus station

If you take a taxi from Syntagma Square or Monastiraki station the first bit of the journey is a little around the houses, but when the taxi enters Liossion Street the road is very straight.  Liossion street is not one of the nicest in Athens, so it can be a bit disconcerting when you head off the main road into small side turnings which you could never believe leads to one of Athen's main bus stations.
But it does.

When you arrive at Bus Terminus B go into the main hall area.  There is a snack bar area off to one side and the ticket hall off to the opposite side.  For the Lamia bus buy a single ticket from the last teller on the right hand side as you walk into the ticket hall area.  Don't buy a return because its better to return on the Alkyon Travel private bus from Agios Konstantinos.  If you need to toilets they are located off the front waiting room directly behind the newspaper kiosk.
