You will start by standing on the doorway of a large bathroom. Turn around, take a step forward and turn left. Exiting this room and walking down the hallway. Passing through doorways and the railing on your right. Keep walking down the hallway until you've reached a room at the end of this hallway. This room is not finished. The walls are still not done. Anyways, in front of you you will see two large windows. Walk towards the left side of those windows. Once you're standing slightly in front of those windows then you're done.
