Designed by architect Carlos Zapata, with razor-sharp interiors by Antonio Citterio, the luxuriously modern Cooper Square (from $255; 25 Cooper Sq., at Bowery; 212-475-5700) rises like a glass wing over the Bowery. Guest rooms are small but thoughtfully set up. Each is stocked with books from Housing Works and a choice of three bathrobes (terrycloth, silk, and yukata) to match your mood or temperature.
