Let there be light. Please.

In the matter of the ideal New York City apartment, many seekers are hot for the sun. Alas, the sun is not always hot for them.

It’s an amenity that many people can’t afford (particularly if, as is sometimes the case, it is tied in with a view and thus commands a premium) or one that expresses itself briefly and rarely, a small square of light in a corner of the living room for seven minutes during the summer months. And sometimes the sun is utterly faithless, here today and gone tomorrow — blotted out by the behemoth going up next door, down the block or across the street. Welcome to New York.

It’s true that plenty of apartment hunters don’t put “light” anywhere near the top of their must-have lists (more about this in a minute), but unless they are descended from a long line of vampires, most people are going to want at least a dappling of sun, if for no other reason than ease of resale.

Then there are those who view light as an elemental need, one that trumps everything else, including location, closets, level floors, an elevator, a doorman and proximity to Trader Joe’s.
