Since it was our first day and we arrived at night, I booked through Klook, and I think it was a great choice. My family said I did a fantastic job booking it! It was clean, the staff was friendly, and we arrived at the hotel quickly. On the other hand, when leaving the country, we used DiDi; the driver was unfriendly, the car smelled bad, and I panicked when Alipay suddenly stopped working (I panicked even more because the driver rushed me, saying there was a CCTV camera and telling me to pay quicklyβI still wonder why Alipay didn't work). When Alipay failed, he claimed no other payment methods worked either, so I paid 200 yuan in cash from my emergency stash and got out. However, Alipay worked just fine again at the airport. You shouldn't compare DiDi taxis to taxis back home in Korea. If there's traffic, they charge you more. Just in case, please carry a little cash with you. I was really flustered. I heard that some drivers even accept Korean won.
