Staring at a wall with a thermostat on it, just to the left is a doorway into an open area and to the left of that is another doorway. Take the leftmost doorway, walk down the hallway towards the grey couch. There's a blue furry rug in front of the couch, walk over that blue furry rug, between the couch on the right and the chairs and desk on the left and walk just so you're standing in the doorway just about to head out to the patio. You're done.
