Anna's place is amazing. It's located easy walking distance from all the wonderful tourist spots in Athens, while still having a the feel of a real neighborhood, with similarly priced restaurants and stores nearby.
Anna herself was fantastic. She greeted us at the apartment, gave us a quick tour, and offered us homemade banitza (savory baked goods) and a small bottle of wine upon our arrival. She showed us a map of Athens, and gave us wonderful advice that complimented our stay. I can't recommend her place enough.
