Look around, you're currently standing on top of a brown staircase. Keep walking up the stairs, passing the brown-framed windows to your right. Keep walking up the stairs, until you've reached the dining room. Once you're at the dining room, you will see a green arm chair to your left. Walk northwest towards the brown table, with brown chairs. Walk northwest until you're at the right-edged corner of the white mat under it, and then you're done.
