We used this apartment for a night stay in Athens. It's very quiet considering being in the capital. Within 20-30 minutes you are at the airport (we used a taxi). The apartment is very clean and with a perfect equipment (which was perfect for us, so we didn't have to use so much things of our luggage.)
The communication with George was also perfect. He is very polite and very helpful.
When we asked to stay some hours longer, he didn't hestimate and made this possible.
We enjoyed our stay and can definitely recommend this airbnb.
