My house is in the center! 5 minutes from metro Sigrou-fix and 10 minutes from metro Acropolis and Plaka with legs!!!! 30 min by Tram from the beach. You can do night walks around Acropolis in a quiet and cute neighborhood. The house is old, we are in the center, but with all you need for a comfortable stay in Athens.
Is very easy to come. Take metro from airport and stop in Sigrou-fix!!
