For a short trip to Athens, my girlfriend and me stayed in Willians flat for 4 days. Willian and his flatmate were very friendly. Especially Willian gave us much information and advices about Athens so that we could plan the day trips effectively.
The flat was very clean and Willian gave us everything we needed like hairdryer, shower gel and towels. We especially liked the big roofgarden. You have a beautiful view of the famous Acropolis from there.
As a conclusion, we can recommend Willian as host for everyone who wants to live in a quiet part of Athens but wants to be in the centre in a few minutes. We would stay in his flat definetly again.
P.S. Cat lovers could live with two sweet cats together ;)
