It was a perfekt stay in Athens.
Konstantinos is extremly helpfull, allways on the spot, very friendly and accomodating. The flat was spotless clean and had everything you need for a relaxed stay. One could even decide to cook proper meals, if only the temptation of all sorts of restaurants , bars and cafes would not discourage the slightes thought.
Metro, bus and taxis near by, plenty of shops of all sorts in walking distance.
This place is highly recomended.
