Excellent all-round !

No clear signage in the airport directing you to firefly in the car park. Despite pre booking I had to wait 1 hour and 15 minutes- not enough cars available. I was told I had no choice of vehicle within the group I had ordered but the colleague beside me was offering multiple choices to other clients who had no booking! Also was charged a 34€ service charge for full to empty ( not very clear on the booking site) despite then telling me that if I return it full I would get the full fuel refund but still have to pay the 34 € service charge!!! After the delay I was told there was no damage on the car - I inspected it and had to return to the office to tell them there were 22 scraps and dents on the car!!! I will never use this provider again! I will be in Spain every week for the next 6 weeks and will use another provider or the bus!!! Not a happy customer at all!!!

The booking platform is good -

It was a long wait in the hot sun ... a water cooler would be good! The car was bigger/better than expected. No pressure to buy extra insurance, just asked if we had it and accepted it. Initially they wanted to charge an old-person supplement but accepted the letter I'd printed from Easy Rent saying there would be no extra charge. I was unaware of the 'service' charge for filling the car (it was full to empty policy) - and how anyone can justify 30euros to take a car to a garage and fill it up is unbelievable! Return was easy and we were told we'd get some cashback for the fuel that was left - I've no reason to believe otherwise but at this point (48 hours after drop off) nothing at all relating to this booking is showing on our credit card statement.

Long wait to drop of

I rented this car and chose firefly because of the Promotion of $1 a day. However, it turned out of that going from Spain to Portugal cost me €80, and an extra driver cost me €80. They also charged me some strange amount for gas. In total it turned out to be one of the more expensive car rentals in my life. The line was long, I guess I wasn't the only one who liked the promotion. The staff was ok, although they giggled and chatted a lot more than I thought was necessary. The returning of the car was a smooth and quick process, 10 out of 10.

The booking process as smooth and quick. No complaints here at all. Excellent site.

The hidden fees were not as expected, and quite disappointing. Additional service fees and holds on a credit card seem to be extreme. A credit report check or something less related to almost $1,000 in holding fees is too large - even if they are typically returned. The parking details in the specific area were not as clear as well.
