My friend and I stayed im Athens for 4 days and couldn't have been happier with our airbnb choice! Dimitris and his brother have been super helpful; and even picked us up from the Metro station to walk us to the Apartment. Very nice flat, clean and well located: All the public transportation stops are in close walking distance, so you can get to the City Center easily.
We'd definitley come back here if we were to return to Athens sometime :)
