Never rent from OK Rent a Car! This company knows all the flaws of their rented cars, but they gamble on you not spotting the subtle damages. After you return the car and leave, they email you saying they've found scratches! When I said I would come back immediately, they said they wouldn't charge for a tiny rust spot on the wheel. It's really disgusting! Make sure to buy comprehensive insurance. European rental companies will try to find ways to charge you extra.

The Barcelona airport branch was not great, and they didn't provide me with a paper copy of the rental agreement. The return process at the Madrid airport branch had friendly service, but the wait time for authorization from superiors was very long. They did provide a paper contract and receipt.

Excellent service and considerably cheaper than traditional alternatives

Works well, but you need someone who speaks English to rewrite some of it...

Overall goo good value for the car nice car bonus have a sat nav as well. Website was clear and easy to use

Do not go with ok rent a car! They tried to say I put a tiny scratch on vehicle underneath bumper. I did not do this but as it wasn’t marked on car when I took it out I couldn’t prove it. They were rude and aggressive and no one was willing to talk to me about a resolution. I’m now having to go through a lengthy insurance claim because they wouldn’t let me leave without paying a ridiculous fine and admin charge. The said scratch was less than 5cm and not noticeable to the eye, just a bit rough when touched. DO NOT USE!
