Walk straight, then turn right into the adjacent bedroom. Walk through the bedroom, and wait by the bathroom door.
With the bed towards your left, move forward and turn right to exit the room. Continue past the foot of the second bed and exit the room via the rightmost door on the opposite wall. After passing through that doorway, stop at the doorway to your left that opens into the bathroom.
Turn to your left and walk out the doorway. Keep walking through the next room, past the bed and through the next door. Stop in the hallway, before you have to walk up two steps, and there is a bathroom door on your left and a window on your right.
