Very good location. A lot of wonderful restaurants and cafes nearby. Close to Acropolis (10 min walk), other ancient sites and the National Garden.
I would not recommend this apartment to people with allergies. The panels on the kitchen wall especially behind sink were eroded and if we didn't air the apartment properly I was sneezing all the time. Also Athens are a loud city and with your windows open, you will hear everything that is happening on the streets.
The bed is made from 2 mattresses stacked upon each other. So it is very, very soft and wiggly.
The apartment is big and comfortable, not taking under consideration the sneezing part.
