Dimitris and Diana put the "Super" into "Superhost". They are so friendly and helpful, and the welcome pack they provided was amazing. Arriving reasonably late in the afternoon on a cold night, they made it so easy to settle in.
The apartment is just as nice as the photos and description portray. It has absolutely everything you need for a lovely and comfortable stay, and the location is perfect. So close to the Acropolis, and with the view of the Parthenon from several rooms and the terrace, makes exploring the history of Athens so easy. Don't be at all concerned about the low ceilings in places, I'm 186cm and had no trouble at all. And, the apartment is so quiet at night, which is important to us.
I cannot recommend this apartment highly enough as the place to stay in Athens. You will be very glad you do.
