The service was very enthusiastic. They will recommend you to upgrade the vehicle and purchase full insurance, but it's entirely optional. Based on our group size, they changed to a relatively more spacious vehicle within the same category, very satisfied! Returning the car in another location is also very convenient, as there is a dedicated lane on the airport highway, and you can drive directly to the car return location. The pickup and return procedures are very simple. I highly recommend self-driving travel. Toll highways in Spain are more convenient than in our country; you can pay directly with a Visa card, which is very convenient.
