Upon our arrival to Madrid, we were greeted with an out of control rudeness! When we asked…read morequestions about liability or International Drivers License we got a condescending attitude, eventually threats of security... Raphael threatened to cancel our reservation with his manager while we were on the phone with Expedia and laughing that he will do it first. He was shushing us with finger gestures and not letting us say anything, wouldn't give us his name, wouldn't let us talk to his manager.... was 100% unwilling to help or explain properly!!! We felt that we were discriminated against! We traveled by car all over Europe and not once did we get so much attitude and unprofessionalism!!! Ended up renting elsewhere after shopping around with two companies and both companies were absolutely amazing and helpful!!! Big mistake, SIXT!!! Your customer service or employee training SUCKS!!!

No such thing as normal wear and tear. Decline insurance and you will get a damage claim…read more I have rented with Sixt Spain two times now. First time was for 3 weeks and this past time was for 2 weeks. When I reserve the car I refuse CWD because my MasterCard covers damage and theft. This past rental I took out Tire and glass with 0€ liability. Tire and glass are typically not covered by your credit card. Each time I got to the counter, jet lagged and not fluent in Spanish the agent has tried to scare me into the CDW by telling me that my Mastercard would not cover theft and loss of use etc. CDW costs about 1/2 the price of the rental price and does not eliminate a deductible which is usually $1500. So with Sixt there is no agent to inspect the car with you when you drop it off and both times, without fail, I get an email stating that Sixt found a scratch and I needed to pay for it. The first time my CC coveted it ($160) minus the $35 fee that Sixt charges. This last time Sixt says I scratched a wheel. Seriously, isn't this normal wear and tear? But, I bought tire insurance correct? In Spain tire also means wheel in the definition. Well even though I paid for it the agent had me initial the contract that I was declining all insurance, including tire and glass. So I had paid for it, it was listed on my confirmation, but declined in Spanish on my contract. After a few back and forth emails, btw save ALL your paperwork, Sixt dropped the claim. I firmly believe that with Sixt, if you decline their super CDW they WILL find a scratch or ding and come after you with a claim. Now maybe Hertz and Avis are as ruthless but dealing with a US company when living in the US is a lot easier. I have never had this happen except with Sixt and I have rented a LOT of cars.

Firefly charged us 16% airport surcharge but the booking voucher said it would only be 8%. It is…read moreimpossible to get a response from them since all contact is ignored. They also strongly advised to take out extra insurance directly with them since it would be a lot cheaper. However on checking afterwards it was a third more expensive than with the comparison website option.

Avoid like the plague…read more Collected at Madrid Airport. I had payed for renters insurance through a third party service. When I arrived at the airport I was informed that I had to pay 30 euros per day for additional insurance through firefly, otherwise my mileage would be limited to 150 kilometers per day. This was not advertized anywhere. I rejected the additional insurance and ended up having to overpay for distance, making this not cheaper than a reputable rental company. I elected to pay for my own gas, but was still charged a "convenience petrol fee", in effect, for the presence of a gas tank. The car was in absolutely awful shape. The service was awful, the queues were long. Save yourself time and money, spend more on a reputable rental agency. DO NOT rent from Firefly, it will NOT be cheaper.

Add to this that we waited for over an hour even though we had already paid for the rental made this a really bad choice. Meanwhile all the other rentals were quickly turning over customers. We sat and waited. And waited. We ended up with a nice car. So that was a plus. We returned it dirty and they were cool with that which was nice.
