Not bad.

The return route was difficult to find, causing me to miss my flight and spend over 30,000 CNY to purchase a new ticket.

Excellent service, especially from the Colombian guy who helped me resolve a major issue with my driver's license.

It took three hours to get the car at the pickup location because the car was being reassigned, and the booked model was unavailable at the time. Similarly, the return time was delayed by three hours. Overall, the service was acceptable.

We had to wait three hours to get the car. The reserved Volkswagen Multivan was unavailable, but they upgraded us to a Mercedes Vito for free, and included three complimentary services: half a tank of fuel, no charge for a second driver, and no extra cost for driving outside of Germany. The Italian guy at the front desk was really patient and helpful. Kudos to him! I'll look for you next time! :)
