Kostas place was absolutely lovely. Located in a very convenient location, 10 min walk from the Acropolis and easily accessible to other parts of Athens. There are convenience stores, bakeries & restaurants located close to the apartment.
The apartment in itself is spacious, and well equipped for a short or long stay. Washing machine,dishwasher, iron, and other electronics; detergents, coffee/tea.
Kostas is a lovely host. Even though the apartment has self check-in Kostas came to welcome us in person. He gave us valuable tips for our stay, and came back again to see us off.
I would recommend Kostas to anyone visiting Athens.
