Check out Carnegie. I live there and there’s a bus station in the small borough that will take you into the city in 10-15 minutes. It’s a busway so minimal stops. We have a really nice business district. I’m a photographer/illustrator myself. We have a farmers market in the summer I sell my stuff at.

I’d be interested where you saw Munhall being one of the safest areas. I don’t think it’s particularly unsafe but I’m sure there are safer areas around Pittsburgh.
