I rented a Nissan Almera and got a Nissam Almera. The car was washed. There were same light stains on the back seat, but nothing serious. The people at the rental booth were helpful. I lost my slot, because I wanted to activate my Thai SIM card first and than had to wait for 10 Minutes, because there was another customer. Giving the car back was no issue, also. Just try to park close to gate 8-9 to avoid having to carry your luggage far. I recommend renting with trip and this rental agency (car). Price was good. Fuel consumption around 5,5 liter/100 km. Aircon working ok. The rental guys did not show me how to operate the car. Had to figure out how to open the fuel door by myself, for example (low right side of the steering wheel). Overall a good experience.
Always good to document any faults... see pictures attached.
