This 1910 neoclassical, beaux-arts landmark is known as the ‘hotel of presidents’ (more than a dozen have slumbered here). The 23-story beauty now caters to a highfalutin business crowd. Rooms are urban stylish (downy bedding, white-marbled bathrooms, abstract artworks); several have lake views (about $50 extra). Check out the painting-filled Art Hall on the 5th floor. Wi-fi costs $15 per day.
