We stayed for three nights in Maria & Makis’s place, and we very much liked it and recommend it. It is easy to access (close to a subway station), conveniently located (15 minutes walk to most of the list-see) and was really clean. Maria was really helpful with any questions we had, and even let us pick-up the luggage after the checkout the day we left. The only thing is that if you are an early and light sleeper, the neighborhood and bars around are quite musical until late at night, but it did not bothered us.
