As for shopping my wife can tell you that its very convenient. Walmart, Home Depot and vons are very close. San Ysidro outlets are so close that in order to avoid parking and traffic you can drop off your wife and pick them up in a few hours. Bonita, Otay Ranch and Chula Vista malls are close as well. Distance and time were right in the middle between the Costco on Broadway and the one on H street in Rancho Del Ray.
The best way to assess friendliness and get a feel for safety in any neighborhood, is to drive there at different times of the day and week. Go grocery shopping there, dine out, get coffee, whatever you normally do in your current neighborhood. You'll get a better feel for any area if you visit during the week during and after business hours, and at different times on the weekend. Also use the crime link provided below, or contact the local police station.
