Picking up the key after hours from a key box was incredibly convenient—this should be a standard everywhere! Sixt made the entire rental process seamless, from start to finish. Returning the car was just as easy, with a simple key drop-off that made the process hassle-free. The car itself was in perfect condition, practically like new. I was especially pleased to receive a Volvo instead of a Mercedes, which suited my preferences perfectly. Overall, a fantastic experience, and I would highly recommend Sixt in Luleå, Sweden!
