Just dropped off my rental and it was a fantastic experience from beginning to finish. Anthony at the union station Sixt counter was super kind and helpful. Zero upsell and the experience was silky smooth. My colleague rented from some discount local company on the other hand and he is beyond livid right now due to some scammy issues he experienced. I am smirking at him in satisfaction. Sixt everytime!

I can’t compliment Nick enough for his service and warm welcome. The whole process from walking in off the street onwards was very straightforward. Check in- given the thorough support they provide each customer, was fine and he prewarned us we were coming to collect at a busy time so we didn’t mind the short wait. Car pick up down the block was easy and cars were immaculate. Drop off just as easy. Nick took an interest in our plans and gave us some helpful suggestions and went out of his way. Thank you! We will come back.
