My booking process was excellent! But

Was very busy at the counter so we had to wait for a bit. Nothing special. As always they tried to sell upgrades for insurance and car models, also nothing special. No problems at all with the check in procedure.

Got an even better deal because of the Price Deal Applicator. It works for you when you are busy doing other stuff. Best feature ever!

The counter staff were very helpful on arrival and departure. The car was excellent and reliable. A perfect rental !

First time on the website but will always be my first port of call from now on. Excellent rates and easy to use. Received an email reference extra charges for driving in France which were absolutely as we expected.

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 -

From the beginning the vehicle was not ready, even though I had a reservation for 6PM. I had to wait one hour and twenty minutes. Expect to pay many additional charges. For example, if you decide to take the vehicle for 1 day to another country, they charge you $7.50 for the days of your rental contract (not the days you take the vehicle out of the country [suppose I rent for 30 days in Madrid and want to go to Portugal for one day, they charge you for the 30 days]). They also charged me 26 euro for a “service” fee, which I thought I wouldn’t have to pay since I brought back the vehicle full, but they didn’t care and didn’t want to change the contract “full to empty” to “full to full”. Very unhappy with firefly

Great

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.
