The car rental process was simple without any insurance upselling. It took just 5 minutes to complete the paperwork. After that, you collect the keys and get the car from the parking lot yourself. QEEQ previously mentioned that an international driving permit was required, but that wasn't the case. I confirmed through the official website that an English translation of my driving license was acceptable, and they accepted it without any issues. Furthermore, I booked a mid-size car (expected i40 or BMW 1 series), but they upgraded it to a Mercedes 220, which was great. Returning the car was as easy as driving to the return location, where a staff member inspected the exterior and dashboard in 3 minutes. The final bill was emailed to me the same afternoon.
