Constantine's apartment is perfectly located, in a quiet area but walking distance for the city center and all main sites. The neighborhood has a lot of nice restaurants and Constantine sent us a detailed list of all sights, nice places to eat and were to shop before our arrival which was really nice and definitely a big plus.
The apartment is spacious, nicely decorated with everything you might need for a nice stay.
Constantine was also very responsive, communication was really easy and he was very flexible. Although the check-out time was at 11am we could leave our luggage a little longer to avoid carrying all our stuff around before departing to the airport.
All in all a great place to stay to visit Athens. Thanks Constantine!
