I slept 6 nights in the apartment, its about 10 minutes walk from the Sygro-fix metro station, on the first floor with a tiny balcony that faces the inner courtyard of the other adjacent buildings, the location was wonderful for me,The apartment and building were very quiet and the neighborhood is lovely, there is a supermarket right next to it, cafes, restaurants and bars and within walking distance of the Acropolis Museum and the Monastraki and plaka area . the bed was very comfortable, there was also a washing machine and everything in the kitchen and shower, a surprising bonus was Netflix TV!
The price was excellent and the apartment is definitely recommended, you have to take into account that there is a few minutes walk to the metro but not so bad.
