These are some of the most notable resi sales of the week

An art collector’s penthouse traded for $9.9 million and a venture capitalist bought in Carnegie Hill. Here are some noteworthy residential deals from the past week.

1. The estate of Elizabeth Stafford, a prominent collector of 18th-century French art and furniture, sold her Lenox Hill penthouse at 900 Fifth Avenue for about $9.9 million. The deal included an additional unit for staff on the second floor. The buyers were listed as Harry and Catherine Jean Totonis. Harry is CEO of ConnectiveRX, which works in the pharmaceutical industry. An October article by auction house Christie’s, ahead of a special sale of Stafford’s collection, said walking into the Stafford apartments in Paris and off Fifth Avenue “was to be transported to another place and another time — Paris in the mid-18th century when the art of luxury goods reached such an extraordinary apogee.” Stafford died last year at age 90, and her apartment went on the market in September for $11.75 million, Mansion Global reported. Douglas Elliman had the listing.

2. A co-op at 1125 Park Avenue in Carnegie Hill for about $8.58 million. The sellers were Alfonso and Lindsay Kimche, who bought the unit in 2014 for $7.9 million, and the buyers were recorded as Douglas and Patricia Sacks. Alfonso Kimche is an operating principal at North Hill Capital Management, a private lender that provides commercial real estate bridge loans. Douglas Elliman listed the three-bedroom unit.

3. Jeweler Jane Bohan and her film and TV director husband Jean de Segonzac dropped $4.7 million for a co-op for $4.7 million at 684 Broadway in Greenwich Village. The sellers were photographer Elena Seibert and her husband Alan Goodman, who was part of the team that launched MTV and re-launched Nickelodeon. The unit spans 3,100 square feet and was asking $4.775 million. The Corcoran Group’s Michael Johnson and Hayim Nommaz were the listing agents.

4. Sonja and Jonathan Perkins bought a six-room coop at 19 East 88th Street, near the Guggenheim Museum, for $4.3 million. The seller was an estate that had first listed the property for $5 million in July, according to StreetEasy. Sonja Perkins is a venture capitalist, the managing director of tech venture capital firm the Perkins Fund. She also founded Broadway Angels, an angel investment group comprised of women, and Project Glimmer, a nonprofit that works to provide gifts for special occasions to women and girls around the country. Brown Harris Stevens’ Mike Lubin had the listing, and CORE’s Patrick Lilly represented the buyers.
