I have never stayed in a capsule room before, but heard about them and figured this would be a good chance to check them out. I have stayed in plenty of hostels and this is exactly what a hostel feels like. On Orbitz I narrowed my search down to Hotels only, and this place still showed up, which is why I booked the Capsule.
The address is listed as Glouster Rd, but the entrance to this building is on Cannon St, just around the corner. You will get email instructions on how to BUZZ into the building. Head up to the 4th floor and use the automated check in system. In the email you get, there is QR code, use that to open the door, and don't use the paper receipt you get with a QR code (it doesn't work too quickly).
The room itself looks like a 1 room apartment that the owner converted in this "hotel". There is a kitchen area, washroom with toilet and shower, a sitting area, and on 1 side are the 6 capsules (3 on the bottom, 3 on top) like bunk beds. Each capsule has lighting, AC, and locks form the inside. Glorified bunkbeds is what you, like in a hostel. They were very cool and something to try, but in the end they are just private bunk beds. There was also 1 room, for women only. Also 6 closets to lock your luggage into.
In Hong Kong, the law says that if you hire a housekeeper, you have to provide them with sleeping arrangements. This "hotel" has a housekeeper, she is very nice. Does a great job keeping the place clean. She also sleeps on the couch in this hotel.
