When apartment #3A at River House, the building that shall not be named in listings, first hit the market in June 2009, it was asking $24.5M. Did nobody tell the sellers River House is past its prime? Looks like someone finally clued them in, because after a brief vacation from the market in August, the listing is back?$5 million cheaper. The new ask, $19.5 million, is actually only 20 percent off, and there's still the $8,937/month maintenance to contend with. But the large terrace, fireplaces, library, balconies facing the river, and private elevator landing do make for some nice floorplan porn.
