The apartment is really beautiful and clean. Iris gave us the keys and a warm welcome to Greece, providing us with all necessary information like a touristic office, made for us some coffee with sweets and warmed the water. The flat is located 30 minutes on foot from acropolis, and it's a beautiful walk. If you're traveling in winter, take some warm clothes to sleep in and house shoes.
We left the apartment at 7:30 am to catch our airport express, but the entrance door was locked - so we missed the train :) Please keep it in mind!
