Ioannis is a nice host who takes care of his guests. He's helpfull and he responded in the minute to every question we had. He gave us a lot of advices about where we could eat and drink.
The flat is exactly the same as in the pictures, and even better ! It has everything we needed and is fully equiped.
It is well placed near the city center, and we could reach bearly everything by foot within 15mn.
The only detail is that there is a little bit noise but hey this is what you get when you are this close to the center :)
So we would totaly recomand Ioannis and his flat for an amazing trip in Athens !
