Beware that the smaller rooms are really small for 2 people and the bed is a double which is OK for 1 person but too small for 2 adults. Bed does not provide any support as it sags in the middle. Causes back aches.
Avoid level 5 rooms that has windows facing the back of the front block. It is too close to the walk way on level 5 between front and back blocks - good if you are a smoker but otherwise noisy with staffs and guests smoking at breaks and late at night.
