Really awesome apartment which I've just rebooked for my next stay in Athens because of its central location right near the station. There's is an amazing one-Euro-per-dish Pakistani dive restaurant next door which I recommend you try, and the area is very green. The square nearby does tend to have a lot of young men from refugee backgrounds congregating and they can be a bit... forward, but they easy enough to avoid and I am a single woman travelling alone and felt fine. No wifi which might be a problem for some, but there's an internet cafe next door. The apartment itself has everything you need, is extremely clean, and generally very cute. Fioralda is a sweetheart and lives somewhere else in the building so you'll have all the privacy you need. The train line is one change away from the airport and goes directly down to the Piraeus.
