You will start by standing in the balcony. Turn around and enter the bedroom. Now exit this bedroom through that opening on the right. You will walk past this circular pillar. On your right there will be a black and white painting with blue lines on it. In front of you there is a double door opening. Walk inside this door. You will see a staircase in front of you. Walk towards the room on the left side of the staircase. Stand on that yellow green doorway and you're done.
