Elias is available, accommodating and very nice. When we arrived he gave us advice on where to go and was always available to help us with our needs.
The apartment is simple but perfectly functional. It's about 25min walk to the center of Athens, 10min to several metro and bus stops. There is a supermarket at the foot of the building, very convenient!
The air-conditioning is an almost indispensable comfort with the heat of Athens, and the terrace is absolutely great :)
I highly recommend !
