Dina's flat is incredibly well located; we were only in Athens for 36 hours, but we managed to walk round the Acropolis, Plaka, and Monastiraki many times without requiring public transportation. Her niece Kelly was incredibly friendly and responsive whenever we had questions. The kitchen was well equipped (which was helpful for my special diet) and a list of recommended restaurants, nearby stores, and taxi numbers was provided - anything you could possibly need during your stay. Shower is hand-held without a curtain, which can be inconvenient, but I suspect this is the case in most apartments in Greece.
