I stayed here for more than 7 days, which was a memorable stay.
There are many reasons:
(1) Room heating system was out of order
(2) Wifi connection is so slow and unstable (even slower than free wifi in a cafe)
(3) The staff of the noma just entered the room after knocking once while I was in bed (so creepy)
(4) Elevator was always out of order
(5) On the 6th day, the emergency evacuation announcement came out, and all the hotel passengers were evacuated at 2:30 am.
