We really enjoy to stay at Anna and Efi apartment, it's located at the heart of the city ,close to every tourist places and next to sub way station with the fantastic view of Acropolis,plenty of fantastic restaurants,shops and cafes. You will enjoy for the whole day even in night time it's still lively.
But if you looking for the quite and peaceful place this will be not suit for you but if you looking for city life experience you should miss to stay at this place.
Finally,if i have a chance to come back to Athens,i'll not hesitate to book this apartment once again.
