There were no issues with picking up or using the car. I rented it for just one day, so I didn't purchase their insurance and had a €1200 deposit held. The ridiculous part happened a day after returning the car when €98 was deducted from the deposit. I contacted customer service, and they explained it was a cleaning fee. When I returned the car, it was midday, and the staff mentioned it was the last shuttle before their break, so they rushed us off without properly inspecting the car. I then asked customer service for evidence of the car being dirty since we only rented it for a day, didn't drive through muddy areas, and absolutely didn't smoke or anything like that. It couldn't have been so dirty to warrant a €98 cleaning fee. The photos they eventually provided showed two small spots on the back seat, which made no sense because the two of us never even used the back seat. Finally, after almost two weeks of appealing to the Zuzuche (Car Rental Platform) customer service, they only refunded half of the charge. This whole experience was ridiculous. Here's a tip for everyone: make sure to inspect the car in person and do some cleaning before returning it.
