Bedrooms: 1 Bathrooms: 1 Square feet: 475 Maintenance: $1,135 — There’s nothing childish about this fully renovated, “loft-like” junior one-bedroom high above East 42nd Street. In addition to offering “panoramic” views of the Chrysler Building and the United Nations, this prewar co-op boasts “exquisite” original details such as high beamed ceilings and oak floors, and access to a 24-hour concierge and a fitness center.
