Continuity mistake: In all episodes, shots and zooms from outside onto Mindy's apartment show a different front of windows than from the inside. That includes size (width vs. height), glass patterns and coloring, and distance between single windows. Even the glass patterns seen from outside occasionally change from episode to episode. From the inside there is a door (to the staircase) between the small window to the right and the bow-front. From the outside, space for a door or a staircase is completely missing.
