You are in hall, facing towards a wall. Turn towards your left and you can find a staircase. Climb up the stairs, all the way to the top floor. Now, turn towards your right and move forward. In front, you can find two more stairs. Get down those stairs and turn around. Keep moving forward near to the wall, which has a section, in which you can find a flower vase. Walk beside that wall and go near the corridor support in front of you. Stand there and you reached your destination.
