When I picked up the car, it had only half a tank of fuel. I returned it with a full tank. The rental company acknowledged this but only refunded me 22.08 euros. I believe this is too little. I asked them to show me the basis for their refund calculation, and they said it was automatically calculated by the system and that they couldn't change the result. They suggested I file a complaint on their website afterward. Since it was quite late at the time, I had to accept the refund. The average fuel price in Madrid was 1.35 euros per liter at the time, which means their refund was only for 16 liters—far less than the cost of half a tank. I later negotiated with them through the rental platform for two months, but they insisted on not providing any further refund.

There was no queue when picking up the car and the paperwork didn't take long. The staff assisting us was polite. The company might include some insurance in the contract by default, so if you sign without looking carefully, you may end up paying more when returning the car.

Collection of the car took too long.

I had booked the Volkswagen Touran, but seeing that there were 6 of us ( 4 ladies, which meant there would more shopping along the way, hehe) plus the amount of luggage we had, the lady at the counter was very helpful and gave us the more spacious Mercedes Vito. We had a very comfortable ride throughout our journey in Spain & Portugal, thanks to that lady at Budget.

At pickup the counter staff insisted upon charging me a refuelling charge even though I had booked Full to Full. The Voucher was not complete with Full to Full details. I had to use my own phone to get onto my Emails to find reference to Full to Full. Staff claimed they did not have internet access to do this themselves. Eventually showed them the confirmation and had a new contract printed. Still waiting to see if they refund me the refuelling charge on my credit card. This was highly stressful and meant that I was forgotten about for a long time whilst later arriving customers were dealt with.
