You're facing a wall inside a bathroom, just turn around and look towards the door of the bathroom, a wooden door, head to the door and leave the bathroom sink to your right and as you look out the bathroom door you'll see there's a wooden cabinet in front of you with some artwork in the wall and picture frames on it, walk towards that cabinet and look to the right. To your right side, and right in front of you, you're going to see an open door that leads into an office. Walk towards that doorway and stand just before going into the office, stand right in the doorway and look to your right side. And as you look to the right side, just outside the office, you'll see a glass door in front of you and through a small hallway. Walk towards that door and now you're standing inside the tiny hallway and in front of the glass door. You're done.
