As described,

Very satisfied, the price indeed reflects the quality.

The car was clean and had no cigarette smell.

Besides the typically slow Thai handwriting, everything else was great. They even gave me soy milk and mineral water after the paperwork was done.

The service was good. We added some insurance, so the actual cost was higher than the price on the reservation, around 310 THB per day. As it was our first time renting a car abroad, we accepted it for safety reasons. Budget doesn't have a counter inside the airport arrival hall, so we had to walk to the rental company. Fortunately, it wasn't far, and you can see it right outside the airport. When returning the car, they drove us to the departure hall entrance.

The environment was clean, and the staff was polite. After returning the car, they even helped us get to the airport. The vehicle was quite clean and tidy, and they assisted in recording the damaged parts of the car. They informed us of the basic precautions. Very responsible.
