18 Oct Answer 1 of 2: Is the euro rate in Lima ok or usd is preferred as with better rate? Are big or small notes preferred or no difference?. 19 Aug Answer 1 of 3: Hi everyone, I am planning a trip to Peru next month & will be visiting Lima, Cusco & of course Machu Picchu. Could someone tell me if it will be a problem to exchange Euro bills in banks or licensed Casa de Cambio/ cambistas? Here. US Dollars and Euros can be changed in Lima without restrictions in hotels, banks, exchange offices or on the street. Some places don't accept US$ bills. The safest way to change money is in banks and your hotel, but this will result in much lower rates.
