Barcelona-Portugal-Madrid.

The store has two counters, there were no other customers in front of us, so my friend and I processed at the same time, very efficient and good service.

The paperwork took an hour. Initially, they said there was no automatic transmission available, then they gave me a diesel Renault. The problem with this big car was that I couldn't drive it out of the parking lot, so I had to come back and exchange it. It was quite a hassle. Even though I had already bought full insurance, they still made me buy insurance. Since I don't understand Spanish, they said it was a deposit that would be refunded. I was with my child, so I signed it. Later, when I asked the rental company, they confirmed I already had full insurance. Just a reminder, do not sign if the amount doesn't match when you pick up the car!

They took advantage of us not understanding English, and noted on the rental form that we chose prepaid fuel. When I questioned this, the staff claimed it was a fuel deposit for returning the car at a different location, and it would be refunded if returned full. But the bank charges showed no refund, and they overcharged by $300. No idea what the fee is! Never renting from Hertz or Thrifty again!!!! Currently trying to find out through the rental platform what the $300 charge is for.

It took some effort to find the drop-off location. See the comments below. The drop-off was okay, I guess.

The return office was closed and we were sked to drop off the key in a box. This leaves the customer feeling insecure as the vehicle isnt checked for scratches etc.

The process was painless
