1. The noise insulation is very bad, that the alarm of next room wake me up every early morning.
2. There is no "Do not distrub" door tag or system. So the housekeeping distrub my rest in the afternoon, even I do not need housekeep service that day.
3. On the night of 31 Oct, some other hotel guests knock my door at 0030am for "treat or trick" which is very annoying. The hotel never take care of this and they make noise till 1:00am.
