We stayed in Antonis place for 5 nights in Athens and we absolutely loved it. The apartment is very sunny as described and the location is close to all the historical sites yet as crowded as the central area. Antonis and his partner Christafenia were very helpful and responsive. We arrived earlier than the checked in time but Christafenia offered the flexibility of storing our suitcases, suggested a cute and nearby cafe for brunch and even helped moved our suitcases to the apartment to save our energy and time.
The apartment is well equipped with all the things you need. There are a couple local shops and super market where we bought fresh fruits and bread for making our own breakfast every morning. The neighborhood is quiet but with some very nice restaurants and bars. Christafenia gave a great list of varieties and we did tried some of them! She also gave us suggestions in all the diff areas in the city, i barely had to use tripadvisor or google!
The sun in Athens in July is quite aggressive and all the visiting requires quite some walking so will suggest all the future visitors to bring hats and water with you ALL TIME.
Definitely recommend this place to who ever is planning to visit Athens!
