Simple process, but average car models.

Overall, it's quite convenient. Although I refueled the car before returning it, I was still charged. Be sure to keep your refueling receipts for any future claims.

They added extra insurance without explanation (I had already purchased it during the booking and provided it along with the rental reservation form). They also switched to a fuel-empty return policy without asking. During the pickup process, the staff barely spoke five sentences to me, mainly urging me to sign the contract without showing me the specific terms. It was a deceptive transaction and a very unsatisfactory rental experience. I won't rent from AVIS again.

Due to language barriers, the staff was noticeably impatient and kept pushing additional insurance and vehicle upgrades, despite my original rental including full insurance. This added to the overall cost. On the plus side, there was hardly a queue.

The elderly gentleman at Avis was very nice, but they often don't have the specified model. Upgrades cost extra. If it's not our fault the model isn't available, we might get a free upgrade depending on our attitude. Unfortunately, this time we paid more and got misled.
