Due to language barriers, the staff arranged for a return with an empty tank. When I returned the car, the tank had extra fuel and I was charged. It's unreasonable to expect anyone to guarantee an empty tank upon return! The extra fuel wasn't refunded; this feels like an indirect way to take advantage of renters. It feels like a trap.

Very professional attitude!

The car rental service at Düsseldorf Airport was decent. The lady at the front desk was a fellow alumna from Dortmund University. The Ford Mondeo estate they provided was great, but they charged me an extra 30 euros for the one-way rental. I had asked QEEQ and they said it was included, but the front desk said it showed up in their system. Since I was in a hurry with kids and elderly family members, I didn't pay much attention.

Only a driver's license is needed, no translation required.

Very good counter customer service at airport; For a reasonable charge upgrade to Golf automatic turned out to be a good choice.
