If a convenient location is what you're after, think the Charleston and Rampart intersection is the way to go. You'd actually be next to three of the nicest shopping centers in Summerlin, accompanied by lots of restaurants as well. The intersection is additionally zoned for some really good schools. Try
Camden Del Mar. It's supposed to be the nicer of the complexes.

If you want more for your money, the Sahara and Fort Apache intersection tends to be less expensive. The neighborhoods are a bit older, but I wouldn't say that they're dangerous at all. This intersection hosts a movie theatre, as well as a few boutiques and restaurants, while also offering close proximity to the stuff at Charleston. As for complexes, Wellington Meadows gets amazing reviews, as does Summerhill Pointe.
