Our stay at Asteris' place was perfect. The room is nice and cozy (although it has no key and the door is mostly glass, Asteris respected our privacy) in the kitchen you can find everything to prepare a meal and in bathroom shampoo, soap (and hairdryer!) are provided. In the room you can also find towels. From the apartment you can easily reach the most important places on foot (15 min to Acropolis), metro and tram are nearby. The neighbourhood can be a bit noisy but I would say that at fault are the motorcycles (which are everywhere in Athens), not the location. Wifi could have worked better. Asteris is very nice guy, he gave us some useful information regarding the places worth visit and offered us an umbrella when it was raining :)
