Library Hotel

This bookish boutique hotel is organized on the principles of the Dewey decimal system—each of its ten floors is allocated a category, such as Literature, the Arts and General Knowledge, and each elegantly understated room contains a collection of books and artwork pertaining to a subject within that category. The popular Love room (interestingly, filed under Philosophy) has a king-size bed, an ivy-clad balcony overlooking the New York Public Library and all kinds of reading matter. Nightly receptions dish out wine and cheese, while upstairs in the rooftop bar, creative libations are inspired by Ernest Hemingway and Harper Lee. A massive DVD library is on hand for kids in need of downtime. Rooms: 60.
