In Union Square, where the chaos knob can feel like it’s stuck on 11, it’s sometimes difficult to find a restful place to … rest. The new Hotel G has 151 surprisingly mellow rooms that seem more like a stylish apartment building than a downtown hotel, decked out with simple homey decor and brightened with Etsy accessories that transport you away from the urban hubbub. Art from Mission-based Creativity Explored hangs on the walls and the preserved turn-of-the-20th century building reminds you of the neighborhood’s pre-H&M era. And of course, there are benefits, like adjoining eateries Klyde Café and Wine Bar and 398 Restaurant, so you never have to leave the building.
