Stayed 4 days. The service was the biggest disappointment for me. Overall, it felt not warm or genuine. When I checked in, the front desk agent seemed like she was just trying to get through the process as quickly as possible. She was giving me information, but it felt like she wasn’t really paying attention to whether I was following what she was saying. There wasn’t really a moment where she paused and asked if I had any questions. It felt more like, “Let’s get this done and move on.” There were also a couple of small things that really surprised me. When the bellboy brought my luggage to the room, I gave him a cash tip. His immediate reaction was an audible “Ah?!” It was quite awkward and honestly made me feel embarrassed, almost as if I had done something strange or inappropriate. I’ve stayed at different luxury hotels in Asia, and that was definitely not the kind of reaction I expected. Then, four days later at check-out, something else happened that I found quite surprising. The front desk agent greeted me, took the room key card from me, and then just carelessly flicked it into a pile with the other cards, almost like throwing a playing card.
