I live in Athens. I just want to say Kudos to all the greeks, they are hard worker, simple and unpretentious people. Its so unfortunate that these people need to work long hour.
And the rent here is a problem thanks to AirBNB and greedy landlords, for example i know people who needs to pay €400 monthly rent (not included utilities bills) with their €1000 monthly salary, and at the end of the month they have nothing to save.
I live in athens for a while now, and weirdly enough the best restaurant i found is in the center area, while they might not have the best service because of the customer traffic, the food is consistently good. So please feel free to explore the restaurant around Monastiraki, Plaka and Thiseio (Apostolou Pavlou) area.
