We had a wonderful stay at Dimitri's apartment in Athens. The view of the Acropolis from the rooftop deck cannot be beat! We never met Dimitri but his father helped us check in and showed us how everything worked and even poured us a shoy of homemade Raki for a true Athens welcome.
The apartment is easy to find and in close proximity to everything, while still being relatively quiet at night. We would absolutely stay there again.
