Start down the corridor going straight in the direction of the wooden floor grain. After you pass a kitchen on your left, look directly ahead. There will be a square opening directly ahead, and a doorway leading into a half bath. Go to the doorway for the half bath.
Walk past the mirror on your right, and continue to walk down the hallway. Walk into the room directly right of the doorway in front of you, and stop once you walk in.
Turn around and go down the long hallway. Turn the right corner, and turn left into the bathroom.
