We stayed in Kwnstantino's apartment for 3 days. First day we came to apartment in the midnight and Kwnstantino was waiting for us to welcome. Apartment is very good, clean and neat. Metro is very near. There are hell lot of restaurants surrounded by apartment. Car rental companies( sixt, avis, Europe car) are also very near. I recommend if some one wants stay in Athens they can chose Kwnstantino apartment. Overall it was fantastic.
