Money and Cash point :
Currency: since 2001 the French unit of currency is the Euro; previously it was the Franc whose value was of about 0.15 euro.
Credit cards: all international credit cards are accepted: Visa, MasterCard etc…
Cash point cards are accepted too (Maestro circuit)
Life cost: As the other European capitals, Paris is a rather expensive city, you can economize by avoiding big expenses in the city-centre areas and eating at the international chains.
