The Munich airport branch isn't open 24 hours, they start at 8 AM, and their customer service was quite poor and indifferent.

The staff were very nice.

Scam company! They deducted over 500 euros claiming I didn’t provide a fuel receipt. Zuzuche made no effort to resolve the problem and kept asking for the fuel receipt even though credit card records were provided. I drove just 400 kilometers and refueled for 70 euros, so why deduct over 500 euros? Zuzuche's reason was that fuel and labor are expensive abroad. Ridiculous! It’s fraud against consumers!!! Check Zuzuche's contract; every clause says they’re not responsible. Rent directly from a car rental agency! Never use Hertz, never use Zuzuche! The intermediary always sides with the car rental agencies, ignoring consumer rights. I will defend my rights!

The service was good. Under a strong recommendation from the counter staff and considering the heavy snow, I bought full insurance. However, they upgraded the car model, so overall, it was quite affordable and reassuring.

The return location details are unclear, especially for out-of-town returns. It's best to ask for clarification when renting the car.
