    If I could rate this company 0 out of 10 I would. The customer service was incredibly rude and dismissive. They are super misleading and will not respond to any inquiries from their customers.

    Great Car, nice office located very central, the Agent processing my booking (Anthony) was not only very friendly and polite but also very helpful. Pick-up and return both worked out uncomplicated and smooth. Great Service!

    Was helped really well by Nick. Even though I showed up after closing, he was super helpful and even held my luggage for me. Will definitely rent again from Sixt
