Turn left so you're facing a statue. To the left will be a wooden chair. Walk towards that wooden chair to the left of the statue. Veer right and go around the corner of the red wall and now to your right you should see a set of wooden stairs. Walk up these wooden stairs. Continue through the open doorway at the top of the stairs onto the purple floor. Bypass the futon, the yellow futon on the right and continue straight, bypass the bed on the right. Continue straight. Once you continue past the bed and the small little hallway behind the bed, there'll be a small doorway tucked in behind the wall, you'll be able to just barely see a toilet. Walk up to that toilet, you're done.
