Fantastic place in a fantastic location. I'm in Greece frequently, and Kolonaki is my place of choice when I go. Dennis' place was in the perfect location to Kolonaki square and all the shops and restaurants nearby. It is also only a 10 minute walk to the Plaka and other tourist areas in Central Athens.
Checkin was probably the easiest of all the places I have stayed, Dennis was very responsive and provided a lengthy and informative list of places to go for food, coffee, shopping etc. The apartment was quaint, quiet and clean. I will definitely stay there again. Highly recommend it.
