The only problem was that we were not informed of the very high excess we would be liable for when renting through Europcar: 1250 Euro.
About the service from the local car rental company
Europcar informed us that we would have an1250 Euro excess to pay on any damage to the car, regardless how small. This did not seem reasonable, but at the point of renting we didn't feel we had a choice. This seemed quite high compared to other car rental experiences we've had.
