We had a great time at Efi s apartment:) The apartment is very centrally located, but at the same time very quiet, and literally a few steps from the metro station Acropolis! The interior is decorated with care and a very good sense of esthetics and there is a fast internet connection.
Efi was an excellent host, she provided us with coffee, tea and delicious cookies for breakfast as well as maps and infos for the city.
Communication concerning arrival times etc. worked also perfectly.

I would highly recommend this apartment for everyone who would like to visit Athens! Thank you Efi!
