Go straight into the hallway. Continue straight and slightly right to continue going down the hallway. Go straight until you get to a red curtain. Turn right on the red curtain then turn right in the wood door. Wait there.
Exit the sauna and go to the right side of the room, pass the wooden panels on the right and go right into the clothed archway, then go straight for a second and step into the doorway on the right then stop.
