We've spent 3 nights in Dion apartment, we have really enjoyed it , the situation of Dion's apartment is perfect 5 min walking from the metro and between Gazi the place to hang out at night and all historical monuments to see, it's easy to do everything by walk. Dion was really nice, he told us everything to know about athens and places to Go. The apartment was clean, if you want to spend some times in athens i recommend hou to visite Dion.
