Orient yourselves so the stove top is on your right and the sink, the island with the sink on your left and walk straight. Veer left after the kitchen island and walk into the middle of the open room, keeping the TV stand on your left and the two chairs below the painting on the right. Straight ahead you should see a glass table on the left and a stairway going down on the right. Walk straight between the two of them towards the brown TV stand like thing behind the glass table. Stop before you reach the end of the glass table, turn back 180 degrees from where you came. To the left now you'll see the stairs and just beyond the stairs is an open doorway. Walk into that open doorway. You'll be in a bathroom next to a toilet, turn to the left and walk just out of the toilet towards the cement wall. You'll see an office in front of you now. Walk behind the chair that's in front of the computer and once you're behind the chair, you're done.
