Nice pied a terre: 92nd floor of 432 Park Ave.
I can pretty much guarantee that this will not be bought by an American, but it will be snapped up fast by some Arab prince, Russian oligarch, South American crony capitalist, or some such international low-life. Nice commission for the realtor. I don't really like the layout (no gun room, no servants' quarters, slave quarters, or space for multiple wives/concubines), but the view sounds good.
