Barbara Corcoran’s lightning-fast penthouse sale seems to have inspired her neighbor to list their own stunning Fifth Avenue duplex for $11.5M. Imagine living right above Central Park with five bedrooms, a wraparound terrace, and both gas and wood-burning fireplaces! The building’s 24-hour doorman, fitness center, and city views make it a true Upper East Side dream. With Corcoran’s unit selling in just one day, will this next-door gem fly off the market just as quickly? Would you pay a premium for a slice of NYC luxury like this? Let’s talk dream homes and what makes a city apartment worth the splurge. #RealEstate #NYCRealEstate #PenthouseLiving
