Expansive vistas pan north, west, and south through barely-there walls of floor-to-ceiling windows in this swish penthouse atop the Mosaic at Hermann Park, one of the twin-ish 30-story condo towers across from the park’s eastern edge. Do the panoramas and high-end custom finishes from a 2012 update to the 2008 space merit the listing’s asking price of $2.05 million? It last sold in 2009 for $930K, but back then the FDIC and a group of investors had control of the property following sequential foreclosures on the condo tower and its neighboring rental twin (once named The Montage).
