YOu are going to start inside a restroom. Walk straight to exit that restroom, three steps, and walk to the left of the hallway. Pass the open door, and keep walking all the way down. Pass the restroom door on your left, pass the painting on your left, and you are going to take a left after the painting. You should be facing a desk with two armchairs. Walk to the left of that desk. Once you are in front of the bookshelf and the grey armchair on the left side, you are done.
