Not what i expected!
For me all athens had to offer was the acropolis. Due to their economic situation it is relatively cheap for europe. On the flip side alot of athens is covered in grafiti, empty buildings, prostitutes, drug users using hard drugs on the streets and police are everywhere.
Insider Tip:Spend 1 night max in athens, see the acropolis, syntagma sq etc then head somewhere else mainland or go to one of the islands, mykonos, santorini etc. Also, visit kostas for amazing souvlaki and its only €2.20 (But buy 2) i think the street name is pentelis street.
