Where should I setup a bank account in Athens?

"Before retiring in Athens, expats should be aware of the cost of living, which is higher than in many other parts of the country. Additionally, expats should research the healthcare system in Athens, as well as the availability of medical services and insurance. It is also important to be aware of the local culture and customs, as well as the language, as English is not widely spoken in Athens. Finally, expats should research the local job market and the availability of housing, as well as the cost of living in the city," mentioned another expat when asked about moving to Athens, Greece.
