Pretty good.

The fuel filter light came on, but the rental company resolved the issue promptly. The service was better than Budget in Europe.

The car inspection was exceptionally strict.

Very convenient. There's a counter right outside the airport. The staff's English isn't great, but the procedures are straightforward. Just make a copy of some documents and remember to bring the translated license provided by QEEQ. The staff then takes you to the parking lot to get the car. After confirming any existing scratches, you just take the keys and go. I’d rent a car again next time.

I very rarely complain but for your information the two ladies at the budget desk were the most rude and disinterested staff I have ever come across. For future, I would suggest that they are spoken to so it doesn’t happen in future.
