I was asked to buy full insurance at price of 350 Euro on top of basic 90 Euro. No negotiation. No other choice.

....

The staff had a terrible attitude and couldn't communicate well in English, even with translation software. Their attitude was vastly different from the Hertz staff in Florence.

I was forced to buy snow tires, but the snow tire was a spare tire, which means if it snowed, I had to change the tire myself. The fuel gauge was not checked when picking up the car, and there was only half a tank of fuel left. I filled it up, but in the end, I didn't even use up half a tank. The extra fuel was not refunded, causing me a lot of loss. Actually, the price of renting a car directly at the counter is the same as Zuzuche.

The car was clean, new and actually better then promised.

The only issue I had was on the return when the agent pointed out a scratch in the paint that was the size of a small child's nail, saying this might be an issue of damage... But after talking to the manager, it was resolved.
