We had a great stay here. Giannis picked us up from Petralona station which was very nice, particularly as our flight was delayed. We loved that there was milk, fruit, butter and water/juice already there when we arrived. Communication with Giannis and Petroula was fantastic throughout our stay and it was really helpful that they have a small room to store your bags.
The location is in a quiet residential area which is walkable to the Acropolis. The only thing to note is that the street is quite dark at night. The apartment was compact but comfortable and great for a couple to stay in.
