We had a wonderful time at Efthinia's place. She was a super quick responder! We did not get to meet her for personal reasons but she left her neighbor in charge, Irini, who was a wonderful host. everything is as advertised, there were wonderful touches like cookies and great food for making your own breakfast. A big book with suggestions on what to do in Athens, even a metro card!
The location is fantastic, steps away from the acropolis, near all the restaurants, there is a supermarket and bakery nearby as well if you decided to cook in the very well equipped kitchen. The place was super clean with very detailed instructions, it had a washer too.
We stayed there with our two kids, an infant and a four year old. Efthinia mentioned in her post that it is not child friendly and I would have to agree......but it was wonderful that she was willing to let us stay anyway.
Would most definitely recommend her place! We would be back.
