Roseate House New Delhi

Perched inside Delhi's Aerocity development, a whole mini-city conjured at the airport's edge, this ultraluxury hotel leans into the ambition of its surroundings. Rooms run to warm ochres, rain showers, and oversize tubs, while higher floors add a 24-hour butler in case you've forgotten what it's like to want for nothing. There's an all-day restaurant, a cocktail bar swinging for NYC credentials, a rooftop pool café, and a spa. Hot-air balloon rides, apparently.
