A recently-abandoned home(d and n)

This house is empty, all the furnishings completely removed. From the dusty outlines on the floor showing where the furniture once sat, you conclude the occupants moved out within the past week or two. A narrow stairway along one wall leads down into darkness. This house is quiet enough that you can probably sleep here, if you don't mind the hard wood floor.
The north door is open.
The only obvious exits are down and north.
