Where would you move to around San Antonio?

My wife and I are thinking about relocating to San Antonio. Which part of town is best to live? Looking for something suburban and fairly quiet and safe. Maybe somewhere With newer homes in the 300-400 range. Somewhere with good restaurants, walking paths and Costco would be a plus. I see that means NW SA looks like the best option but I don’t really know the area. Thanks for any suggestion’s.
