We are going to start facing a sliding door. Turn left, and take the opening that is on the right side of the picture. Take two steps to go out to the hallway. Turn left, and take two steps. Pass the painting on the left side. Take another left, and we should see a door opened right before the staircase going down. Take one step to go inside that room, and take two steps to finish right in front of the painting of a lot of squares, black and yellow squares. That is going to be the destination.
