This mammoth three-story brick home once belonged to the Oneida Community, a utopian religious group founded in 1848. Today it houses private rental apartments, a museum, and eight large guest rooms, most of which feel like a bedroom in one's own home. Most rooms include comfortable upholstered chairs, and the decor throughout is tasteful and restrained. You may stroll through the more than 33 acres of lawns and gardens that surround the mansion. The restaurant serves up tapas and other rich dishes.
