Willian is a great host and has a wonderful flat. Pretty convenient to get to the metro to see any of the sites and an awesome view of the Acropolis. Pack lightly though as it's definitely an uphill walk from the metro and an elevator to a higher floor. He was extremely accommodating even with my odd flight times. He has two wonderful cats as well who are very friendly - one's more shy than the other. He speaks English well and him and his flat mate are happy to socialize and/or provide advice. I'd thoroughly recommend to anyone wishing to stay in Athens for a few nights.
