Very professional rental car operation, unlike many other places you find in Berlin. As always. the quality of service can only be fully assessed once here is a problem. I did have a problem once, and it was dealt with in the most professional and rapid matter. They even significantly reduced charges on a final invoice, which is actually a quite unusual behavior in this industry. I have tried pretty much all different rental car companies in Berlin over the years - and this is the best. By far!
