Stay Away. It's a rip off. A car rental in Athens that was supposed to cost €209, became a super expensive rental of around €555 and a terrible customer experience. 1. Paid extra €80 on a forced upgrade we didn't want. Our flight was 4 hours late. Although we paid the rental in full in advance, when we arrived they said our reservation was cancelled and we must pay for the upgrade. 2. Received a 15 years old car with a cassette player, without 4WD and no USB. The car was damaged from around. 3. Bringing the car from Green Motion far away office is an extra hour to take into consideration while all other car rental companies are at the Athens airport. They forced my family to wait at the airport so I had to drive back to the airport and look for them. 4. Extra €105 for charging the deposit instead of holding the deposit on the card - In the "credit card and deposit information" on the voucher we got it is said: "A deposit amount of EUR 1488.0 will be held against your credit card for the duration of the rental". The deposit was not held on our credit card. Green Motion charged our credit card with €1488 deposit. When we returned the car, they paid back the deposit. As our credit card is foreign, we had to pay extra €105 for foreign currency exchange fees. I rented cars hundred of times. This is the first time a car rental company actually charged my card and in this case it is a breach of their own agreement. Note that if your credit card is not from the Euro countries, you'll also pay such fee. 5. Paid €160 of extra fuel consumption - The old car we got had a crazy fuel consumption of 20 litters to 100 km, much higher than the Toyota Rav4 we were supposed to have. During our trip we drove around 1500 km and the extra fuel cost above what we would have paid if we got the Toyota was around €160. 6. Total rip off: €345 above the original €209 this rental was supposed to cost + hours of driving back and forth to the airport + the low leveled service we received and the feeling we were deceived. We learned our lesson. Better to rent a car from the more mainstream companies that have desks at the airport.
