I imagine it resembles an old gypsy hovel of discarded and yard-sale furniture and questionable decoration (don't forget the framed pictures of I, Nadin hanging on the walls).
I would guess the opposite, except for numerous photos of the heroine herself, possibly even a small shrine or two in her honor.
Furniture-wise, I'd expect the nadinlair to be as spare and spartan as can be imagined. Her husband, if indeed he exists, was a career submariner, not a life that encourages the accumulation of a lot of junk. Nutcase nadin herself, being deeply involved in global salvation and promoting the dictatorship of the proletariat, hardly strikes one as a
hausfrau. Physically, she's well along into her babushkahood, but with zero domestic skill or interest.
