Konstantinos was a great host, ready to help and accommodate and to answer even the silliest of our questions; that made us feel very welcome. The apartment is located perfectly if you want to visit Acropolis; the rest of what you may need is also just a short walk away.
We have visited in the middle of August, so it was very hot - and cooling the apartment was a problem, especially since we tried to switch off the air conditioning after each hour; if it's not so hot, then it's not gonna be a problem.
