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.

Everything went smoothly with the rental and return. There are two issues to note: 1. The map indication for the Budget rental location in Madrid is incorrect. There is no rental point in the city center, only at the train station. Fortunately, I confirmed this a day in advance. Also, during the rental process, the car rental staff will inform you that the driving license translation provided by QEEQ is not legal in Spain. They can still rent to you, but if any issues arise, the police will treat it as driving without a license.

Very convenient, great service! They upgraded our vehicle.

The car pickup and drop-off went very smoothly. Pretty good.

A very pleasant car rental experience. I booked a Volkswagen GOLF, but they gave me a BMW 1 Series with only 3200 kilometers on it, essentially a new car. The staff at the store were very friendly. They checked my driver's license, notarized documents, passport, and I prepaid the deposit with a credit card. All the procedures were completed in less than 5 minutes. When returning the car on Sunday, the store was closed. I just parked the car in the designated parking lot and put the keys in the box at the door. Very convenient.
