Looking for the Ottoman Sultan

The Ottoman Empire ended in 1923, replaced by the modern Turkish Republic. But the Man Who Would Be Sultan is still alive and living in New York city.

Ertuğrul Osman V, or Devletli Necabetli Ertuğrul Osman Efendi Hazretleri, was born in 1912. He was in line for the Ottoman throne and was in school in Vienna when the last Ottoman Sultan Mehmed VI was deposed in November 1922. The House of Osman had ruled Turkey and its possessions since 1281.

He moved to Manhattan in 1939. There have been other titular post-imperial heads of the House of Osman, with theoretical rules lasting:

Name	Born-Died	Reign
Abdulmecid II	1868-1944	19 Nov 1922 — 23 Aug 1944
Ahmed IV Nihad	1883-1954	23 Aug 1944 — 4 June 1954
Osman IV Fuad	1895-1973	4 June 1954 — 19 May 1973
Mehmed Abdulaziz II	1901-1977	19 May 1973 — 19 Jan 1977
Ali Vasib	1903-1983	19 Jan 1977 — 9 Dec 1983
Mehmed VII Orhan	1909-1994	9 Dec 1983 — 12 Mar 1994

However, Ertuğrul Osman is the last Turkey-born head of the House of Osman. And so, at least in theory, the last man able to hold the title of Sultan.

An article in the New York Times describes his home as "on Lexington Avenue in the 70s, above a restaurant", in a 3rd-floor walkup in a building otherwise non-residential. Osman and his wife, Zeynep, a niece of the last king of Afghanistan, live in an apartment owned by Stephen Kirschenbaum. "After they married in 1991, Osman's apartment, with its 25-by-40-foot living room and huge terrace facing a leafy backyard, was the obvious place for them to live."

Well, that just cries out for investigation.

So, somewhere below is a picture of the home of the last Ottoman Sultan. I'm not sure exactly which picture shows his home, but a couple of places seem especially likely to me.
