Athens is the city of philosophers. People sit at cafes sipping wine, eating Greek salad, and contemplating about lives. And for some reason, you will find cats to join your philosophical path in every corner of the street. They are literally everywhere, as a solo hunter, as a cat pack, and they are extremely fluffy and clean. A heaven for cat lovers, seriously. Recommended route: walk from Monastriaki Square up the hill to the Acropolis.
