As you're facing a thermostat on the wall, you have to turn around and walk towards the brown table. Once you get a little bit past the table, you have to make a right turn. You should end up in a kitchen. Go around the grey or silver trashcan next to the island. Continue towards the living room with the yellow couches and make a left turn to go up the stairs. When you get to the second triangular step, that's gonna be your destination.
