We loved our stay at Antonis' Sunny Design Apartment. It was an ideal location from which to explore Athens, with the Acropolis within walking distance, a metro line station around the corner, and shops for groceries only a few minutes away.
There was also a variety of bars and restaurants very close within walking distance, and Antonis was very helpful giving us a lot of recommendations on where to eat and drink.
The check-in was seamless, and the apartment was well equipped, with a lovely balcony, and very comfortable for the two of us during our week in Athens.
Overall we would definitely recommend to a friend and would consider staying again if we revisit Athens!
