The painting and the love affair are interesting, but, as a landlord, I found myself wondering: How does an apartment remain untouched for 70 years? How was the rent paid without interruption? How were rent increases handled (or did the rent remain constant for 70 years?)? How did the landlord not have to access the apartment when the other parts of the building/infrastructure were renovated/upgraded over the decades? Also, Pigalle was/is a bit of a rough neighborhood, so why wasn't there a break-in over those 70 years?
