Bernal Heights is in the southern part of the city, bordering the Mission, Glen Park, and Noe Valley. Bernal is a very community-oriented neighborhood and is a very friendly place to live.
It's also very dog-friendly, baby-friendly and home to many young couples or couples with kids.
It's got a somewhat artistic but gentrified, ramshackle but gorgeous air. It's like your favorite bohemian cousin.
