Facing the tables with the chairs on them, take a step towards them. Then jump towards the far end of that table on the other side of the red chair. Now you're on the other side of the table, walk, facing the bathtub walk to the left and up those two steps. Then continue right up the stairs that you can see in the distance and stop half way up that first flight of stairs so you'll be on about the 5th or 6th step from the top, you're done.
