There's plenty of safe places in that area. Though I would steer clear of Warminster Heights - I think that's the area I'm thinking of - last I knew, there were a lot of drugs in that area. But otherwise, I can't think of a bad or unsafe place. I lived in the nearby Hatboro/Horsham area when I moved out of my parents place and they wouldn't have allowed me to live there had it been unsafe. I lived in the Blair Mill Village Apartments (East) and they were great:

But I don't know if you're looking for an apartment or a house to rent.
