NoHo is ok. Kind of a transitional neighborhood. Used to be a bit blue collar but with relatively low rent and easy commute to Downtown LA via subway, lots of young people are moving there. It's also very close to Burbank (Disney and Warner) so there is a fairly high concentration of people employed in the creative industries.
The main street (Lankershim Blvd) used to be a deserted wasteland but with the subway and Orange line opening, and concerted effort to revitalize the area, the area around the subway station has become one of the more interesting part of the Valley.
