Interrent pressured me into paying 299 Euro insurance after informing me the 1400 Euro would be taken even if there was the slightest scratch on the car when it was returned. Fuel deposit of 110 Euro was excessive. Dd not receive Qashqai but a larger Peugeot. They would not inspect car on return to verify I had refilled. Would never use again, totally felt ripped off.

As above, interent staff insisted I purchase extra insurance saying I was not fully covered on the insurance, cost me £200 extra, not happy!

The instructions said the office was opposite check in desks 165-170, there are no offices there. Got sent here there and everywhere by staff at Madrid airport and eventually found the office on a different floor! Mentioned this to the man on the counter and he just shrugged and said they knew it was wrong! He was very rude, in a bad mood, unhelpful, not at all friendly, very pushy trying to sell me insurance I already had and told me they were blocking one amount from my card and then blocked more. He also lied to me, telling me the amount would be blocked for 30 days, trying again to get me to sign for the insurance. When I returned the car they confirmed the balance would be unblocked within 2-3 days!

Very quick and easy.

The reason for choosing this provider was that it stated pick up was within the Terminal. This wasn't the case. A shuttle bus to the rental location was involved. I wanted to avoid a shuttle bus due to having a small child and lots of luggage.

Very good.

There were a lot of hidden costs that we were not informed about upfront, including a mandatory €1000 deposit if we didn't pay out for the extra insurance cover, and a €102 fuel deposit (which is more fuel than will even fit in a Fiat 500). Staff also didn't tell us about these costs in one go, even when directly asked 'what is the total we will have to pay'. This created a really negative experience for us and impacted on a lot of our holiday plans. It seemed like this was intentional, a way of forcing people into paying money without giving them the full information in advance, and it felt like we were being scammed. It was also contrary to the information that we received from our broker, Easyrentcars.com, which advised that we could be charged a maximum deposit of up to the equivalent of $500, meaning that we were missold this car hire deal. In future I will avoid Interrent and recommend that others do also.
