We had a great stay with in Rio's apartment. It was a lovely, very clean studio apartment off a nice pedestrian walkway. The position was great - it was close to the Acropolis and Plaka and we walked our way around central Athens from the apartment. Maria, Rio's wife, met us when we arrived and when we were leaving. She was very friendly, gave us a map of Athens and pointed out some good areas. She even recommended a nice restaurant just 2 minutes away where we had some of the cheapest and best food we ate in Greece. The only reservation I might have in recommending it to everyone is that the stairs to the bedroom are quite steep so if you have any mobility issues maybe it's not for you. However for us, it was ideal and we would happily stay here again if we are ever back in Athens.
