Overall pretty good.

I booked the car a month in advance, but when I went to pick it up, I was told that there were no Golf or similar cars available and that I needed to upgrade. After upgrading, I got a Polo, which made me seriously suspect that this was a malicious charge (there were cars available, but they told me otherwise to charge an extra fee for an upgrade, and it was actually the same car).

The waiting time was acceptable and the explanation was clear. However, no one helped us install the child seat, so we spent a lot of time on that. We sought their help, but they were short-staffed and couldn't assist.

There were only two groups of people picking up cars, but it took a long time. The charged amount at pickup was higher than the order amount, allegedly a deposit, but it wasn't refunded for a long time. When returning the car in the evening, there were no staff available for discussion. The only positive was the convenience of returning the car.

The service was enthusiastic, and picking up the car at Zurich Airport was convenient. However, if your English isn't good, it can be quite challenging.
