The counter staff were quite friendly, their English level was good, and they even personally assisted with the car pickup.

The staff were rude, seemed like they had an argument with someone earlier

With Hertz, there were quite a few people, but it was still manageable.

When returning the car, we were required to fill up the tank. After doing so, the fuel gauge still didn't show full, and they charged us without explanation. Fortunately, we noticed and went back to dispute it. We took the staff to the gas station, filled the tank again, and the gauge still showed one bar less, causing us to waste money on extra fuel, as the automatic machine didn't give change. Going back again for a refund wasted a lot of our time.

Consistently excellent: car condition, service attitude, and the staff even helped with luggage. Great!
