I checked in to two rooms around 11:00 PM after a trip from Yogyakarta. Unfortunately, one of the rooms had a fishy odor that was quite disturbing, making it uncomfortable to stay in. I immediately complained to the receptionist and asked for a room change. However, the complaint handling process felt ineffective. We were asked to wait quite a long time, then the staff came to check the room and then asked us to wait again to call housekeeping. Being extremely tired after a long trip, we naturally hoped for a faster and more efficient handling process. After a long wait, we were finally given a replacement room, but it was on a separate floor, which was quite inconvenient. Hopefully, in the future, complaints handling will be more responsive and considerate of guest comfort, especially during late-night check-ins.
