4. Chelsea
Chelsea is smack dab in the heart of the city, but it's somehow retained a close-knit community vibe. It's known for its LGBTQ+ friendly nightlife, but there's definitely something for everyone. Art galleries, restaurants, the High Line, the famous Chelsea Market - it's got it all. The apartment buildings (many of which include rooftop access), are full of young professionals.
