The neighborhood along Monterey Road was coming up quickly during the boom. The PLANT shopping center was built, Starbucks on Moneterey, new homes off of Wall Street and the like. Although the overall rejuvenation has slowed down a bit in this economy, I do believe this will continue to become a better and better neighborhood.
Crime reports. com is a great site to look at. If you look at this zip code, look at others that are considered "safe" like 95125 to compare. Also, my best suggestion is to go to the neighborhood at different times of the day. Talk to the neighbors, people around and ask about crime etc. Have breakfast at Just for Breakfast. One of the best breakfast places in San Jose.
