Secret playroom behind wardrobe
This reminds me of an apartment I once visited in San Franciso. There were two refrigerators in the kitchen. One was normal and the other was a secret door. Walking through it led you to a dark hallway that ended in a small room with a single chair in the middle and a single lightbulb hanging down over it. Creepy as hell.
