This is NOT a hotel (HK govt is working on forcing this kind of places to brand themselves "hotel") Think "Bed space". It is for people who are short on cash and does not care about where they stay. there is no space, aside from your bed (~3/4 size of a twin mattress), and a "wet room", which is toilet/shower/sink all in one.
Put it this way, when you sit up from the "bed", you should be stepping all over your luggage, and the luggage will hinder the main entrance door, thats how small the room is.
