You're starting in what looks like a boiler room, facing a water cooler. Go through the door that's next to the water cooler. This will take you into another room. There is a wall with many boxes just sitting at the bottom of it. Take a step up toward those boxes. Then off to the left, you'll see an open doorway. Near that doorway are more boxes with a white bust on them next to a green door. Take a step toward that bust. Then there will be stairs to your left. Take a step up the stairs. Then you'll take one more step up to where it bends and basically where the brown railing begins. So, you'll basically be in the middle of the staircase. You're done.
