Remember that Athens garbage includes toilet paper as the waste pipe bores are too narrow to accomodate flushing them down. Living within another culture. Has its ups and downs. However, you are living in Athens. The Athens which fathered democracy, philosophy, and generally influenced all of western civilization since the Classical Period.
Sidewalks are too damn narrow in many places.
If you have the money, there is fantastic shopping here, especially for fashions. Shop in the Kolonaki district with its hundreds of expensive boutiques and shops. Too many cars. They are parked everywhere too. You will be dodging around parked cars on the sidewalk.
