Any suburb near the Walkingstick golf course is beautiful - large homes, big yards, swimming pools. They tend to be a little pricier than the rest of Pueblo, running about $500,000, but the neighborhood is lovely, very clean, and very safe. It's also conveniently situated next door to CSU.
The Westgate suburb off of Pueblo Blvd is also a nice community. And even though it's a bit of a drive from the main city of Pueblo, I'd recommend looking at Pueblo West. This is a planned community just off Hwy 50; it's small, but there are a lot of nice subdivisions there. Pueblo West also has several schools and plenty of businesses, but it's still only a 15 minute drive from downtown Pueblo.
