good service overall but make sure you check the vehicle to avoid any charges on return

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 -

El coche supero las expectativas. Amplio y muy comodo.

The staff were helpful friendly, polite and best of all there was no upselling.. I was in and out within 10 minutes.

Website was easy to use, I would definitely be using their services again. Highly Recommended !!

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.

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
