One way to reach the apartment from the airport is to take the metro (this is the blue line). In Monastiraki station you change and take the green line (direction to Kifissia).
Otherwise you take "proastiakos train" from the airport, you get off at "Neratziotissa", you take the metro's green line (direction to Piraeus). Normaly that's the fastest way.
At any case you get off at the station called: "Ano Patissia".
You walk above the railway. This street is called: Chalkidos.
Two streets after the traffic lights (you'll see a store with motorbike accessories) you turn on your left. That's Sevron St.
All this lasts about 5 minutes (from the metro station "Ano Patissia" to the apartment).
