I loved staying at Eugenia's ! She is so kind and welcoming! The apartment is charming and nice ! The location is very practical, 10 minutes to Sygrou's Metro station, The Acropolis and Plaka's area are really close - one metro station. Neos Kosmos is a very authentic area. It's very easy to catch transports to the center and to the Piraeus. I will definitely come back to her place next time I am in Athens !
