best neighborhoods to live in manhattan in your 20s?

hey all! west coaster here moving to nyc, i've never been there even though i'm at 15 countries.

wondering where is the best neighborhood for a young and social girl moving to nyc-
i love meeting new people and exploring new restaurants, museums, art, etc etc

i found a good apt in hell's kitchen, but have heard more young people are in chelsea, soho, tribeca?
