We had an amazing time in Athens. First because it's Athens, second because of Kostis's incredible place, and third because of Kostis and Liz's recommendations. From the booking to checking out Kostis was always a text or phone call away to answer any questions. He checked on us by text to make sure our visit was going well and to see if we had any questions. He and Liz are real professionals.
The apartment was just as advertised, very nice, very clean, and in a perfect location underneath the Acropolis. The rooftop at night is a must see, with a beautiful view of the Parthenon lit up. The location couldn't be better as you are in walking distance to just about everything.
Pro tip. Try Kostis's recommendations on the restaurants in the area. Everyone we tried was spot on.
I can't recommend this place enough! We will definitely be back.
