I visited Athen the first time with two of my friends and it was a very good decision to take Kostas apartment. We had a real good stay and felt very comfortable. The apartment was clean, everything we needed was there and the view over the roofs of the city to the Acropolis was great.
Kostas is a good host, who wants you to have a nice stay. He gave me a perfect description how to get to the apartment and picked us up from the nearby metro station, so we didn´t need to search for the way. He also had many other good and helpful information for us and helped, when we had questions during the stay. He is very well prepared with that.
I can definately recomend to stay there.
