Wai Yan was a great host! Before I asked, she provided me with clear instructions on how to access the location. The place was minimal, but it was very clean when I arrived. I think it was exactly what I was looking for for a 1-night stay. The building entrance is slightly off-putting (I got approached by a man standing at the entrance to book a room for the night, in fairly aggressive Mandarin), but the unit and hotel part was as expected:)
