You are going to start facing a white shelf. Turn to the right, jump over the couch double door that is closed in front of you, and go up the stairs. Take the hallway towards the left and get inside the room that is on the left of those three paintings that you should see ahead of you. No need to go inside that room, we are going to peak inside and that's it. Turn to the right and walk past the console table on the right and the three paintings on the left. Turn right after the console table and get inside this room. Three more steps to get to the bench that is below the window. Once you are there, next to that bench, you are done.
