Alexandros's place in Christoumou is a great place to stay in Athens. It is very quiet as it is in a side street and very central, we walked everywhere and only took a bus once. The apartment is clean, spacious and warm (we were there in January) and had all the amenities you might need for your stay in Athens. It is very conveniently close to a Hammam and a great Taverna (Saita). We will definitely come back to it.
