Airbnb was looking like described. Nice place to stay there one night or a few. Huge plus for location- the way to Syntagma metro station is just 2 minutes away from the apartment and if you need a good communication with Airport, I can fully recommend it. Another advantage is a Netflix option on TV.
Unfortunately, the worst thing was a terrible noise from the outside :( Even when windows were closed - the sound is very loud. I could not sleep all night...
