You begin looking towards a desk with a world map on top of it, and a radio. Turn to your left and move towards the open hallway to the left of the double doors. Once you're at the head of that hallway, just turn left, and you're going to move down the hallway to the left of that hallway. You should pass a little picture that says closer, or 'objects may be closer than they appear', if you wanted the full text... As you step into the door at the end of that hallway, you're going to just turn straight back around and move into the bathroom to the right. Once you are inside that bathroom, step up just next to the tub, and you're done.
