Right now you're facing the glass door. Turn left and move forward, now you're facing painting on the wall. Turn right and move little forward, now you're facing a black couch in front of you. Turn left and and you can see an opened door. Exit the room through that opened door. Now you can find a narrow passage in front of you. Walk through that narrow passage till you reach an narrow entrance in front of you. Now slightly turn right and you can see a portrait on the wall. Move towards that portrait and that would be the end point.
