I've been using airbnb all over the world for over half a decade and I can not stress enough that this was the best one I've ever stayed at.
Unique layout with great design choices with a fantastic location in plaka with easy access to all the great sites around the Parthenon and national garden. The room tucked away from the noise was calm but when you left you were half a block away from a vibrant neighborhood full of life and good food.
I recommend art bar for a great drink and it is a bit of a trek about 20 minutes walking avli was a great restaurant.
Our host was not only incredibly accommodating setting up rides from the airport and to the port, but recommended great locales nearby such as Brettos for some ouzo which you have to try when in Athens.
Again, great stay and would highly recommend.
