Beware should anything go wrong. Received a great quote w/ an easy reservation process (quote CF7976AB). When we went to pick-up the car in Athens on July 4, 2019, the local agency wouldn't honor the rental as I didn't have an International Driver's License (I've rented twice in Italy in the last 6 months without one so wasn't aware). Yes, this was buried in the T&C's on Carflexi's website but wasn't cited in the multiple advance emails listing out the required documentation (they cited the following: voucher, valid credit card, drivers license, ID/passport). In-the-moment support was terrible: slow chat offering no helpful info, leaving us stranded w/ no car...it took multiple taxis, busses and 5 additional hours to get us and the kids to our destination. Follow-up support continued to be a disaster, lost all of my $672 deposit as they were of no help, took no accountability and "hid behind the fine print." Ended up going directly to Sixt and had a great experience: they gave us the info needed to get the necessary license in a matter of hours online and ultimately gave us a better price on a slightly larger car. Going direct with the rental agencies is definitely the best way to go...unfortunately this was an expensive lesson to learn.
