The best thing about this place is the location, right in the middle of the action. And endless amount of popular restaurants, across the street from a huge mall, 1 minute walk to the MTR station, etc.
The place is tiny, which is normal for Hong Kong. Some perspective – I'm 6'2" and could lay on the bed and touch the four walls with my hands and feet.
We didn't interact with the host at all, everything was automated, no problems there.
It seems, at least one of the rooms in the Inn is being used as a storage and distribution center for some kind of retail goods reselling operation. This wasn't a major concern for us, but weren't really discrete about it.
To be clear, during our stay – we would often find people outside of our room, in the hallway and adjacent rooms moving around, packing and unpacking suitcases full of shopping bags... we found it a bit strange, as I think most guests would.
