The stay in Arhens was great.
The owners of this house are really nice persons, kind and hospitable.
About the apartment, you will find everything you need, it's really clean and well equipped.
The position is great! You are close to Syngrou Fix station that is just one stop of subway from the Acropolis (that is possible reach also by foot in 10 minutes) and two from Syntagma square.
Next to the apartment there are also the main services: super markets, pharmacy and bakeries.
I advice you to visit this wonderful city and especially to chose this house to spend your holidays.
