The apartment fits the description and is situated in walking distance from Monastiraki (20min or so). The terrace is cool and it`s the best asset of the palce from my point of view. The attention to detail can be easily noticed and the apartment is cozy and nice.
Dimitris helped us with a late check-in due to missing our flight and he was always available to help us during our stay.
I would recommend Dimitris and his place when visiting Athens.
