No problems with Auto Europe, however some problems with the car rented from Hertz.
About the service from the local car rental company - HERTZ WEND
Fluid for windshield did not spray, had to stop several times to clean it with the snow. Rear one worked properly. Hertz offered a discount voucher CHF30 against future rent a car from them however only in Switzerland and within one year. Chance to use it practically nil.
