Willian wasn't here during my stay, but his flatmate took great care of me and my friend. He was very accommodating - our flight was super delayed and we arrived at the apartment at 2am in the morning, but he still came down to greet us and explained how everything in the apartment works with great patience. The apartment's as awesome as the description seems to be! You literally get an unobstructed view of the Acropolis. The interior's nicely designed etc. And the stay comes at such an affordable price! I couldn't recommend Willian's place any more highly.
