Exit the bathroom. Turn right and go down the stairs. Wait at the end.
Walk out of the room and turn right. Walk into the hallway and turn right. Stop at the bottom of the stairs.
Look at the open doorway outside leading out of the bathroom and head through it. On the left there is a double door and on the right is a pathway towards a rectangular window; take the right towards the rectangular window. Once at the window, turn right and head down the steps. Once you've reached the bottom of the steps and see a kitchen on your right, you've reached your destination.
