Eleni's apartment was perfect for our three day trip to Athens! We were able to take the metro straight from the airport to Syntagma Square which is only a short walk from the apartment. We were checked in quickly and the apartment amenities and area were explained very well by Eleni's helper Kelly. The apartment is located in a very quiet neighborhood right by Plaka and is walking distance from the Acropolis (decent distance, but very scenic!), Acropolis museum, Central Market, and Ermou.
The apartment was clean, spacious, and comfortable. We didn't take advantage of many of the amenities, but the kitchen seemed well stocked and had plenty of room to cook if you desired. Kelly was also extremely helpful and took the time to help book a transfer for us from the apartment straight to Pireaus Port early in the morning before the metro was running so that we could catch a ferry.
I would definitely stay at Eleni's apartment again if I was visiting Athens again in the future. Highly recommended!
