Wonderful hosts and wonderful location. Within view of the Acropolis and an easy walk from the Metro. It's a 40 minute journey from the airport, roughly.
The hosts are wonderful--Stefanos came to the metro station and walked me ot the apartment when I was having some issues with directions, and Antoina immediately came and helped me figure out the washing machine since I desparetely needed to do laundry. Furthermore, they printed my rental car confirmation for me! Really full-service folks. Highly recommend for a good, spacious home base in Athens.
