Nice flat in a convenient location. It is just few minutes walking from the Acropolis metro station, in the lively neighborhood of Koukaki, with many facilities at a walking distance (supermarkets, cafes, bars and a laundry self-service just in front of the house).
Just two very small issues: the neighborhood can be noisy at night during weekends, and you need to switch on the boiler 15 minutes before you need hot water.
Stephania is really helpful and gave me many suggestions about my stay in Athens. Efharistó!
