Who is Sheri Donatti from Kafka Was the Rage: A Greenwich Village Memoir and what is their importance?

When Anatole Broyard first came to Greenwich Village seeking a place to live, he became acquainted with Sheri Donatti. Sheri was an abstract artist who lived in an apartment building in the Village and owned a second apartment in the same building. It was perfect, Broyard needed a place to live and Sheri needed to rent her place. Upon seeing the apartment that was for rent, he realized that something was amiss since it was jammed with her possessions—which she failed to explain. Only after he moved in did he realize that they were cohabitating.
