Do not rent with this branch (or any Hertz Germany branches). Their customer service is TERRIBLE. We had a rental for an entire month and the Europaplatz branch’s phone lines were down FOR THE ENTIRE MONTH. I had no way to reach them, so I emailed and my emails apparently went to spam. We ended up having to take a 45-minute metro journey to go down to their office so they could answer our question (and discover our emails in their spam inbox). We even tried calling the Hertz Germany line and they tried to reach them and couldn’t get a hold of them. How do you run a company without phones?!
What’s more, when I asked to return the car 4 days early, they told me there would be a $14,500 charge because that put us under a month and kicked us to a daily rate. While I understand the logic, this is clearly impossible and ridiculous since I wasn’t even asking for a refund of the 4 unused days. I had to spend 7 hours calling Hertz customer service in Germany, Dublin, the US, and Munich before I finally found someone willing to help get the price back down to what it was supposed to be. I nearly had to cancel my plane tickets in order to babysit the car and settle the problem. I have rented cars with many companies in many countries. Never EVER have I had as much trouble as I’ve had with Hertz. Pay for the upgrade and use a more reputable company. You will be glad you did.
