Maria is a great host, very thoughtful. Her place is very clean and quiet and comfortable. The X95 bus from the airport has a stop a few blocks from the apartment; it also goes to Syntagma square. There is also a metro station a little further just a ten minute walk. Both are named Ambelokipi. If you are sensitive to this—nobody has been smoking in the apartment itself but there are smokers in the building which sometimes you smell (like almost all of Greece).
