Travel Note
Greece uses Euros (can be exchanged at the airport for a fee, or from an ATM), and many places in Greece accept all major credit and debit cards.
Travel Note
On average the weather in Athens will be in the 60s Fahrenheit in November. There is a good chance of some rainy days during that time as well. It is a great time to visit Athens during the off-season of tourism, where there are less people and generally lower prices than the summer.
