On an historic and typically lovely tree-lined Upper East Side block between Park and Lexington Avenues, this sprawling 2,400-square-foot duplex co-op at 125 East 74th Street is as elegant and old-school as it gets, with modern interiors and laid-back charm. The listing points out the “European style and flair” of this classic eight, asking $4.25 million, with four bedrooms upstairs and plenty of entertaining space below; according to records, the home’s current owner is Charlotte Sarkozy, ex-wife of Mary Kate Olsen’s husband, financier Olivier Sarkozy (who is also former French President Nicolas Sarkozy’s half-brother). As if that weren’t enough of a pedigree, the building was also Jackie Onassis’ childhood home.
125 East 74th Street
It doesn’t get much more classic Upper East Side than this two-bedroom, sixth-floor co-op on a quietly elegant street just off Park Avenue. The limestone-anchored 1928 building at 125 East 74th Street, designed by Lafayette A. Goldstone, as the NY Post informs us, was the early childhood home of Jacqueline Kennedy Onassis. Unit 6A in this pretty prewar building is on the market for $1.39 million. Famous associations aside, the gracious layout of the apartment, which started out having eight rooms and was reconfigured to its current five-room state, looks to be a pretty good deal for the price given its size and location.
