You're going to start facing a window and door number 328. Turn 90 degrees to the left, and take that hallway until the end. Follow the curve to the left, and keep going, following the exit sign. Follow the curve to the left again, and this time we're going to take a left turn, and go inside the room with a bunch of black chairs. This is like a conference room, it has a wheelchair as well. Turn to the right inside that room, and walk to throw left, to the right side of the chairs and the glass wall. Walk until the end towards the white desk and black chair, turn slightly to the left, and there should be a open door between the two desks and between, and on the left side of the picture frames. Once you are there standing in front of the, of the door, no need to go out, just between the two white desks, you're done.
