We had a fantastic stay at Aris' place.
Aris was a great host and was very welcoming. The place was clean when we checked in and stocked with some food and alcohol for our stay. It is easily the best location we could have hoped for, right near the Acropolis and Monastriaki which is a great area to visit nice bars, restaurants and the flea markets. The pictures do not do the view justice. You could see so much of Athens and the view of the Acropolis was amazing.
The only place to stay in Athens in my opinion.
