I recently had an exceptional experience with Sixt in Naperville. The staff exhibited a remarkable level of friendliness and dedication to assisting customers in the best possible manner. I found their rates to be highly competitive, and as a repeat customer, I've consistently been impressed by their service. Regardless of the issue, they consistently resolve it with efficiency and professionalism. Special commendation goes to managers Alejandro and David, as well as front desk agents Shelly and Jasmine, and check-in agents Mohammed and Liyum, all of whom have consistently exceeded my expectations.
