Eleni's flat is very near the Acropolis and the Acropolis Museum!! The neighborhood is quite diverse and working class, but never felt unsafe!
You MUST dine at Piato el Greco just up the hill 1 block and turn right for half a block. It's on the opposite side of the street and the owner is a sweetheart!! We were only at the flat for less than a day and went back to this restaurant 3 TIMES!!!
