Nice place in a great and safe location in Kolonaki. Close to metro station (beware of pickpocketers!) and walking distance from many must-see places. The neighborhood has plenty of cafes, grocery shops, restaurants, and cute shops.
The patio was a perk, even though it never gets any sun. The entrance passage that leads to the apartment could do with more lighting though.
Maria was always ready to answer all of our questions which was very much appreciated.
