You begin looking at a pair of wicker chairs. Turn around to your left and move into the doorway to the left just in front of you. Once you are through that doorway you should see some glass shelves directly in front of you on the wall. Turn left and move into the door on the left corner. The one between two other doors. Once you are inside that door it should be a sauna, step into the middle of the bottom of the sauna, and you're done.
