The rental company's attitude was acceptable.

I was conned into buying 2 sets of insurance, absolute disgrace

The car was just what was needed for the couple of days I was in Las Palmas. The whole experience was good, except for the fact that the insurance cost (80 EUR or a 900 EUR deposit) and the fuel deposit (another 80 EUR) was hidden until I arrived to pick the car up. Not the most unreasonable pricing, but disliked the underhanded way it seemed to be hidden until I had little choice but to pay it. Would have been much happy had it been included in the original cost when booking online.

We had previously rented with Interrent in Tenerife, so I knew what to expect from the car - a very small Fiat 500, but it was very cheap so that was OK. It does seem that one of the reasons that Interrent is cheaper is because their desk in the airport and where the cars are located are about the furthest they can be from Arrivals!

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.
