My narrow corridor.. the unit nez to it is ours.. the door + the window panes nez to it is the width of the living room.. is miserably small.. but rather cosy.. and juz for interest.. we tied the garbage and leave it at the side of the door.. the garbage collector will push a trolley to collect everything in the late evening... there is a post "hole" on the door.. so the postman delivered letters and dropped it into ur flat.. juz a slice of a common HKer life :p
