Terrible!
My experience with Next Car Rental was absolutely dreadful. The woman at the registration desk was incredibly rude and unhelpful. After finally directing me to find the car, it turned out to be locked and inaccessible for 40 minutes. During this time, the woman disappeared without any assistance. Additionally, the rental price initially quoted was doubled upon final payment, making it the most expensive rental I've ever had. This was a completely impractical and awful experience overall. I strongly advise against renting from them.
