App response is fast during daytime, luckily I don't need help at night which I encountered no response before check in, since it is a counter-less hotel. Room design is nice by making full use of space, but cleanliness could be an issue, as very dusty at the fitting near window. My wet wipes were rather dirty even at 2nd wipe. Wondering the aircon flow is good or not, as I clearly see layer of dust on kettle cover and part of surfaces at night and clearer the next day. During Covid-19, cleanliness and aircon flow are rather important, hope I am fine!! Also, I feedback twice for the potential fire hazard due to charging battery operated foldable bike at the corridor. Bike was removed almost immediate after feedback, but appearing again the next day, meaning overnight charging. This hotel is shophouse with narrow corridor, and many fire incidents about overnight charging bike. I wonder what is the meaning of waiting for management instructions, as someone can just unplug the bike and put it in storeroom. The guest will surely ask the hotel when the bike is missing, rite?? Good that I am still in one piece, instead of kena BBQ becoming famous delicious Singapore SATAY!!
