Do not use the EuroNet ATM in Monterosso
I made the mistake of withdrawing Euros from this machine with my Canadian dollar debit card.
I ended up being charged terrible rate for a Euro to USD conversion and then got screwed again when my bank converted the USD to CAD.
I specifically rejected the request to be charged a fixed rate when prompted to by the ATM - maybe the machine is rigged to ignore the customers response.
The ultimate rate I charged should be considered illegal and EuroNet seems to be operating without ethics.
