The place was perfect for our family (parents + six kids) - we had one bedroom to ourselves and the kids were all in the bunk room. It was in the 90s, and the kids could keep their room nice and cool since it was separate, while we could just sleep with open windows. Kitchen was well stocked for a family that likes to cook - cool morning meals in the dining room, and evening meals out in the courtyard. Two bathrooms was great, too.
The area was fantastic - not at all touristy but with a hip square just around the corner (baker, pharmacy, food shop, + any number of cafes and restaurants). Close to Petralona Metro stop (~ 5 blocks) but we walked to the center each day since the path lead straight through the Filapappou archeological district. In effect, each morning and evening we walked the 3,000 year old road into and out of Athens through a massive park by ourselves...Talk about getting a sense of history - the kids ran around picking up pot sherds! Each evening we would go to the top of Filapappou to look back on the Akropolis from the absolute best view in the city - by day, sunset, or evening.
Stavros, our host, was just as gracious and attentive - remaining in constant communication even as our extremely late flight meant that we did not make to the house until around 2 in the morning - but there he was to great us!
