We loved staying at Katerina's apartment. The view of the Acropolis is as advertised - you actually cannot believe it is that great of a view, but it is. We sat on the deck and in the apartment just staring at it!
This was our first AirBnB experience and Katerina was a perfect host. She met us at the apartment to go over everything and left some nice local treats for us to enjoy. She was responsive and offered to assist us with transportation from the cruise terminal to the apartment and again to the airport. She also alerted us that there was a taxi strike the day we were arriving and coordinated transportation with the host from our friend's AirBnB to ensure we had a van ready to pick us up.
This apartment is situated in the heart of a vibrant city that seems to not sleep until the early hours. You can literally go down the elevator onto the street and find coffee shops or restaurants up and down the street and neighboring streets - all within easy walking distances.
And, a complete bonus for any knitters traveling to Athens...there is a wonderful established yarn store in the same building before you go up to the apartment. I spent some time there and left with some beautiful European yarns.
