This place is the best for a long stay and true experience at Athens. I stayed for about a week and really enjoyed the neighbourhood as well as the location of the apartment: every morning on the way to the Acropolis, the city centre and almost every other important ancient place, you can walk via Philopappou hill that offers a nice walk and a spectacular panorama of the Acropolis, while the neighbourhood is not a touristy place at all, but still offers a lot of nice restaurants and tavernas.
The apartment was clean and very spacious but still cozy, the kitchen had everything for basic cooking, the living room perfect for relaxing and the WiFi stable. While staying at Athens, temperatures got up to more than 40 degree celsius and the two air conditioners managed perfectly to provide the apartment with a chilly breeze.
Plus: Anna Maria and Dhimitri were very nice hosts, offering a welcome basket with wine and snacks and were always quickly responding and eager to help with everything.
I would choose this apartment for the next trip to Athens again - definitely recommend this place!
Ευχαριστώ πολύ!
