How is the triplets' home described in the book, One Two Three: A Novel?

The Mitchell House is the house where Mab, Monday, and Mirabel live with their mother, Nora. The house has two stories, and the girls share the dining room as their bedroom because Mirabel cannot navigate the stairs. The house is not very large and is incredibly cramped because Monday has become the town's “librarian” and has all the books that were discarded when the real library closed. The house is important to the members of the family because it provides a sense of security.
