They required I believe 500HKD for room deposit. We had not gotten our HKD just yet and instead had to put down 100USD (which is more than HKD when converted). The front desk does not speak much English and aren't very welcoming. It is a little hard to find, on google I believe they note this hotel as previously named A Hotel.
Location otherwise was pretty close to the main roads for shopping in Mongkok. The best part of this room is the rain shower, roomy shower with great water pressure. The separate toilet room was not as clean as the rest of the room (corners of it), but still cleaner than the other hotel we stayed at in Hong Kong. Beds are a little hard and the view isn't spectacular. We only stayed a night for our flight out to Taiwan, but it was sufficient enough.
