Kostas' place is great and in a privileged location. His flat was super clean, towels, coffee, tea, everything needed. Plus he welcomed us and showed us also the terrace - what a view of Acropolis! His street is full of restaurants and bars, walking distance from main spots and close to a subway. The building is an old one which turns into something even more interesting. We had a great time and would definitely stay there again. Again, definitely worth staying.
