Just make sure its a visa or mastercard. AMEX and Discover are less accepted over here.

Call the credit card company and ask what their international transaction fees are. Some are only 1%, but will often apply to even debit cards at ATM machines when getting cash.

Other things to consider:

What is the length of your stay?

Do you plan to open any local accounts (checking, savings)? If so, a credit card from the local bank might also be easy to manage.

Do you currently manage your accounts electronically? Making everything "no paper" will save you from having to worry about statements getting lost between here and there.
