Here's the listing via Corcoran:
The location of this house within the St. Mark's Historic district cannot be more picturesque than where Stuyvesant Street meets East 10th Street. A wonderful and truly magnificent early Federal House that was built in 1795, for Nicholas William Stuyvesant, the great-great-grandson of Peter Stuyvesant. This house has immense historical significance as it is the oldest building in Manhattan that has been used continuously as a single-family house.This is an elegant home ... with large rooms that possess beautiful proportions it also has 8 fireplaces. The scale of the house allows for extremely gracious living with 5 bedrooms and 4 and half bathrooms plus a formal dining room and a great artist studio that is 23' x 28' with a skylight also known as the atelier with soaring 12.5' ceilings! A lovingly landscaped garden is here too. This house has never been on the market for sale before. This is an exceptionally unique opportunity to own a piece of Dutch New York history — a true treasure!
Asking price: $8.9 million.

And the house was on the sales market very briefly last year, but the listing was pulled.
Anyway, here is some more history from a February 2022 feature at the Post:
Back in 1795, Nicholas William Stuyvesant — the great-great-grandson of the 17th-century Dutch colonial officer and governor of New Netherland (which became New York and New Jersey), Peter Stuyvesant — built the house for his wife, Catherine. The couple raised their nine children in the house, and more than 200 years later, it remains Manhattan's only building from the 18th century used purely and continually as a residence.
And via Atlas Obscura:
In 1969, the house was designated a landmark as part of the St. Mark’s Historic District. At this time it was one of the oldest houses to be used continuously as a residence in Manhattan. It rivals the Jumel Mansion and the Dyckman farmhouse as one of the oldest homes in the city, but it is certainly the furthest downtown.
