Clinton Avenue Memoirs - S5-E16
Continuity mistake: The front door of Sophia's former apartment is on the right wall, under the stairs. The fireplace is on the far back wall to the left, next to the foot of the stairs. But in the earlier episode, "A Piece of Cake", the front door is next to the stairs, there is no fireplace, and Sophia's bedroom door is where the front door is in "Clinton Avenue Memoirs".
