The apartment was clean and eclectic. It is within walking distance of many popular locations. We loved the little kitchen and living room area.
The only drawback was that there were parties at bars below us a couple nights in a row they were very loud. Otherwise the communication with the owner was fantastic and they were very helpful.
They even lined up a cab driver for us from the airport to the apartment on our first morning arriving. That was extremely helpful since we had never been to the country before.
For Americans be aware that toilet paper cannot go into the toilets in Athens. It has to go in a garbage can. A little bit of a mindset change.
