To be honest, this company surprised me quite a bit. I had initially chosen another company closer to departure, which was cheaper, but when I went to pay, it suddenly showed they were out of cars. After refreshing, this company with low ratings was the only one left. I took a gamble and booked it.
We arrived at Bangkok airport around 2 AM. There was only one staff member at the counter, and they weren't even one of their employees. Because we mistakenly forgot about the time difference, we arrived two hours early and had to wait until 4 AM for them to bring the car. The car wasn't as dirty and messy as many reviews suggested, but the power bank and a pack of tissues left inside indicated it hadn't been cleaned much.
Overall, the car was in pretty good condition. I got used to driving on the right-hand drive in about half an hour. Returning the car was also smooth and without any problems. Maybe I just got lucky? Anyway, to be honest...
