Willian is a great host, always willing and very able to help in anyway he can from booking taxis and ferries to giving you information about good places to visit. His apartment is ideally located for visiting the Acropolis, walking is fine if you are fit. The apartment is very clean and comfortable just as shown in the website. A highlight is to sit on the balcony and look at the Parthenon as you are having a meal. I have no hesitation in recommending Willian's apartment as a place to stay while in Athens.
