The apartment is very nice, not just for sleeping. It is located about 5 minutes away from the metro station Ambelokipi, from where you can quickly reach Syntagma Square. It is an apartment that I would definitely book again.
Philio is a very helpful person. She asked me several times if everything was right during my stay.
Philio (and Diana), thank you for the hospitality during the week I was in Athens.
