Andronike replies replies to emails asap (in a matter of minutes in our case). She made it easier for us by letting us drop our luggages a few hours before the actual check-in time, so we could roam free and light in the streets of Athens without our load or luggages. She was not there but a friend of her was and introduced us efficiently to everything we needed to know.
Abut our 2 nights stay : It is well located (close to Acropoli metro station, to the museum of the acropole, to the acropole, to plaka...), it is easy to find also. It is quiet. It is clean. All the facilities u might need.
To be honest, there is absolutely nothing to complain about. Everyting is as described in the airbnb profile and even better. If I really had to say somehting, it would be about the kitchen that does not really have room for a bench top (if u need to cook on your own). Overall = 100% satisfied, will come back :-)
