I am happy to inform you that there are three ATM machines working in Alykes - Alykanas for this summer season:
One in Alykes car rentals (Alykes office), one in Alykes car rentals (Alykanas office) and one at Montes super market.
The two first are from Citibank and the last is from Alpha Bank.
Hopefully this will make your stay a lot easier.
