This has been my second experience with Airbnb and I should say everything went smoothly.
Faye is really a very professional person. She answers immediately and check-in and check-out have been very efficient.
The flat offers - as many others highlighted - an amazing view of the Acropolis.
The area is full of nice bars and restaurant. The Acropolis museum is just opposite and to get to the airport by metro (provided you selected the right timing) it takes no more than 50 minutes all inclusive.
Strongly recommended
