Athens is a city full of contradictions. Acropolis pedestrian ring is a bliss while city avenues are just full of noise and loud traffic. This is an alive metropolis with half a dozen of million people in, working, going to their job, sightseeing etc. It is not “doable” on a day or “just like that”. Athens needs planning. Everything, meaning museums, metro system, food, sightseeing are there. Nevertheless cannot be discovered “just like this”. You ‘ll have to do some basic homework before.
