We were greeted by Maria, super nice lady (she organised our transport to Kefalonia, booked the taxi and bus/ferry transport for us. Otherwise we wouldn't have know exactly how to get there).
The apartment is perfect for a solo or couple, bed is good, aircon was upstairs. Perfect location, 5 mins walk to Temple of Zeus. 8mins from Acropolis metro, and about 10-15mins to the Acropolis.
The shower doesn't have any enclosure so take care not to slip. But all is clean and tidy.
Overall great experience, totally worth it. Book!
