A rarely offered full-floor Fifth Avenue co-op has surfaced at 845 Fifth Avenue, asking $30 million and presented in what the listing describes as “mint, museum-quality” condition. The roughly 7,500-square-foot, five-bedroom residence occupies the entire second floor and comes with a separately renovated ground-floor guest studio.
What's on offer
The apartment keeps a classic prewar layout built for serious entertaining, with a monumental dining room, dual galleries, and a chef's kitchen that opens to a breakfast room and service wing. The listing also notes a pantry, laundry, gym, and four staff rooms, along with custom millwork, parquet de Versailles floors, and original moldings that lean into the building's pedigree. As listed by Douglas Elliman, the $30 million offering measures about 7,500 square feet and includes the ground-floor guest suite.
The residence advertises two Central Park-facing living rooms, a large “Her” room and a more intimate “His” salon, each with wood-burning fireplaces and direct park views. The secondary room is currently configured as a billiards-and-bar salon, while an oval library and an unusually wide dining room round out the entertaining suite. “I've never seen a dining room as large or as wide as this one,” listing agent Emanuele Fiore told The New York Post.
Listing particulars and building notes
The offering appears on MLS as RLS20074359 and is being marketed by Emanuele Fiore of SERHANT., with the listing syndicated across several platforms. The building, generally known as 4 East 66th Street, dates to the 1919 to 1920 era and sits directly across from Central Park, a combination that tends to keep demand high. The Xome posting emphasizes the private elevator landing and full-floor proportions that set the home apart from more typical Upper East Side apartments.
Who lived here
The listing ties ownership to the late Alan “Ace” Greenberg, a longtime Wall Street executive and Upper East Side resident, as first reported by The New York Post. Greenberg's career and years at Bear Stearns are documented in his obituary for the Los Angeles Times, which notes he served as CEO beginning in 1978 and later as chairman.
Where this sits in the market
Full-floor Fifth Avenue apartments are rare currency and have fetched marquee prices in recent years. One full-floor closing at 845 Fifth reportedly reached roughly $52 million in 2016, underscoring the premium buyers pay for scale and provenance, according to The Real Deal. That earlier sale, alongside other headline transactions around the Upper East Side, helps put the current $30 million ask into perspective for prospective buyers.
For now, the apartment is being offered intact and largely turnkey, a combination that could appeal to collectors, large households, and anyone chasing a museum-quality Fifth Avenue home with modern systems. The listing is handled by Emanuele Fiore, and more on the agent and team is available via his SERHANT. profile.
