I can only recommend the Cityfahrschule Aarau. Driving instructor Mr. Christoph Konrad is competent, gave me valuable tips and was patient.
Response from Cityfahrschule GmbH:
Super driving school. Already VKU, motorcycle and car testing done here. Car with Timo, extremely friendly, patient and competent driving instructor. The first attempt passed the test with 12 driving hours. I highly recommend it!
I can recommend the City Driving School 100%. I think it's great that this driving school also offers the VKU and the emergency course in addition to the driving lessons. Thanks to my driving instructor Timo I passed the driving test the first time.
