This is the view from room 1013 of the Standard, André Balazs’s new High Line�straddling hotel (from $195 a night; 848 Washington St., nr. W. 12th St.; 212-645-4646), designed by Todd Schliemann of Polshek Partnership Architects with décor by Roman and Williams. It’s spectacular, as you can see, and thanks to the floor-to-ceiling glass, all 337 rooms have perspective-delighting views over the city. This might seem an odd time to open any hotel, much less the 39 scheduled for this year, but there are benefits to the room boom.
