I stayed at Willians place for a few days with a friend of mine and we just had an amazing time there. Reaching his apartment was super easy. It is close to the central area of athens (walking distance) and well connected to public transport. The apartment is quite spacious and very clean. The best feature is the huge penthouse balcony with a view on the Acropolis. Willlian is a fantastic host and was always there to help us and give us advise on nice things to do and where to go. We hope to come again
