Finding a quiet boutique in a big city might seem like a challenge, but in reality, some of our most intimate stays are tucked into the corners of the world’s largest metropolises. Offering personalized service and charming details, these petite hotels — most have less than 20 rooms — are some of our favorites. So if mega-metropolises such as Buenos Aires, Hong Kong, and Los Angeles might intimidate you, fear not. You can always retreat to these intimate boutiques for some quiet time amidst the bustle of the big city.
