It’s an incongruous sight, this sleek glass tower sprouting above its low-slung brick neighbors, but you can’t argue with the results — the views from the rooms, even on the middling floors, are extraordinary, taking in the Financial District, the downtown bridges, even the midtown towers, depending on your room’s orientation. And the rooms themselves are surprisingly luxurious, with flat-screen televisions, CD stereo systems and access to a carefully curated DVD library, along with low-tech charms like Frette linens and robes and, in many rooms, private terraces from which to take in the jaw-dropping views.
