Elena's flat is incredibly central and easy to walk to most areas in Athens. They efficiently maxed out the space and balcony is incredible. Its a comfortable space for two. She responds quickly and had one of the best showers I had while in Greece. The people who run the coffee place downstairs were also incredibly helpful as well. You are definitely right in the city center so there is a fair amount of city noise but I think that comes with the territory of any place that is so centrally located.
