We stayed 4 nights at Rose's place, and we really liked it. The room is bigger than others in HK, and the location was our favourite out of the three that we tried throughout our stay in the city. It's very local, very close to the metro and bus stops, excellent food options very close by. It's also very secure with many locks to lock the room.
A/C and hot water worked perfectly, there's a little desk/table and water boiler.
Only two things we didn't like. First, the bed is very small, specially for 2 people (most beds and bedrooms are small in HK, but this bed was particularly so. Also, I would suggest the host adds some sort of courtain or screen to prevent the city's bright light to get in the room for better sleeping.
The place is great value and we would stay there again.
