John was extremely helpful, waited for me and my group late at night until we arrived from the airport, gave us great tips and lots of printed maps and guides of the city. The apartment has everything you might possibly need and even more for a short stay (in our case) and longer one as well. It is in the centre of the city, 3 minutes from the Acropolis and other attractions are accessible on foot, we never had to use the public transportation. We could not be more satisfied with our choice of accommodation.
