Overall, no issues. Everyone was very enthusiastic. However, the car's power was lacking, overtaking was almost impossible.

Circular staff at Nevşehir Airport were very unprofessional. The rental form had no contact details, and there was no office within the airport. We waited outside the airport for half an hour before the staff finally showed up. This company requires you to write down your credit card's security code, not just a simple pre-authorization! When we tried to negotiate, the staff was very rude. They also charged an extra 29 EUR for one-way rental and 3 EUR for airport fees, despite us having full insurance. Furthermore, they don't have a designated drop-off point at Ankara Airport; you need to contact the staff by phone.

The service provided at both pickup and return was acceptable. However, since the communication about the pickup location was mainly handled by the customer service of Zuzuche, I believe that the inconvenience and additional costs caused by the confusion regarding the pickup location are not related to CIRCULAR CAR HIRE.

The pickup reception was average, followed the standard procedures, and the entire self-driving trip was smooth.

At the airport, there was someone in the arrivals hall to assist with the car pickup. They charged an additional 30 euros for returning the car at a different location and requested a 5-euro tip. Since we arrived at the airport in the early morning, we felt it was appropriate to tip for their trouble. Shortly after leaving the airport, we were informed by a gas station attendant that there was an issue with the tire pressure. Kudos to the gas station staff who filled the tires for free. Given that almost everything costs money back home, we insisted on tipping. After driving for a few hours, one of the tires blew out—a car with 100,000 kilometers on it likely never had the tires changed, as the spare was worn down. We paid 300 lira when returning the car but received no receipt. They said a digital receipt would be emailed the next day, which we have yet to receive. Fortunately, we followed the advice from Zuzuche customer service and got a written proof from them. We are now in the process of claiming insurance. Hopefully, it will go through. We're glad we bought full coverage insurance, as a tire costs nearly 900 RMB. Sigh...
