As a general rule, a luxury rental apartment in Manhattan is something of a prize. Some Manhattan rental apartments are more prized than others, and more prized by some NYC dwellers more than by others -- no fee NYC rental apartments are both rare and money-saving, which gives them some obvious value; the appeal of green rental apartment listings is no less obvious. But with New York City sweating out what is turning out to be one of the hottest summers on record, a new type of Manhattan rental listing has surged to the top of the list of most desirable NYC rental properties. In the New York Times, Sam Dolnick describes the appeal of the ultilities-included rental apartment, in which the absence of apartment-specific electricity monitoring enables round-the-clock air conditioning blastage. So, is the utilities-included rental apartment the new holy grail of Manhattan rental listings? Or is it just an especially inefficient way for some NYC dwellers to create a huge, 66-degree carbon footprint for themselves? Who says it can't be both?
