My friend and I stayed in this lovely apartment from 13-20 June 2017. It is exactly and shown in the pictures. The two balconies (you are on the 6th, last, floor) are marvelous.
We did not get the chance to meet Michalis and Irene since they were out of the country but we were welcomed by their co-host Stelios, wonderful person, very kind and helpful.
The place is very clean and there is everything you may need (there was also a big bag of ice which was a lifesaver on the really hot days).
It is a very short walking distance from the Panormou subway station which is just a few stops from the center.
I will 100% come back next time I'll come to Athens.
Thank you for the lovely hospitality :)
