We have been using Airbnb all around the word for years, and Eleni actually is one of the very guests we have ever met !
Her place, first, is perfect : very well located, quiet, perfectly clean, decorated with taste and equipped with everything guests need.
Elena is besides a fantastic host, welcoming, full of tact (she had filled the fridge with fruits before our arrival), talkative, interesting (she taught us a lot about Greek culture) and full of relevant advice about her city (and I can assert that it is true, as I happen to know Athens well, where I lived decades ago).
We definitely recommend her !!!!
