As you're facing the plant and the windows looking outside, turn around. Walk past the dining table towards a wall painting to the left. Make a left at the wall painting down the stairs. Leading you into a larger seating area. Walk past the sofas to your left. Once you see the flight of stairs leading downstairs and an open brown door, head downstairs. You'll see a black metal gate to the right. Enter through that gate. You'll see a room full of wine bottles. You'll see a brown table and two chairs once you move past those, in the corner will be your end destination.
