Very nice place if you want to walk around the center of Athens. Everything so close so you dont need to use metro. Akcopolis is 15 min. by walk and also very good restaurant is 5 min. by walk.
One minus is missing air condition if you want to stay longer during very hot days because it is so hot inside of flat.
Vassilis and Rallou are very helpfull if you need any tourist information. If I am again in Athens I will ask for rent here :)
