Petros' apartment was absolutely amazing.
We arrived 30 mins early but through open and easy communication, we were able to check in as the apartment was ready in time. Him and his assistant were very friendly and accommodating.
The apartment itself was very clean and in a central location near 100's if not 1000's of restaurants, walking distance to many attractions (i.e. Acropolis, Hadrians Library and the Roman/Ancient Agora).
Whenever we had any questions, it was very easy to get a hold of our host and we would definitely recommend staying here.
