Which neighborhoods in San Diego are within walking distance to shops, near Navy Base?

Shops meaning grocery stores, post office, banks, etc. able to walk to/from. Considering either Balboa Park, or National City, somewhere near the Navy Base in San Diego. Which neighborhoods should I avoid renting? Thank you.
I’m considering civilian work with the Navy.

If you’ll be working at the naval base you’ll want to aim for living in Point Loma. It can be pricey, but not always. It’s a great community–safe–and you can walk to the post office, bakeries, grocery stores, etc easily.

My other favorite neighborhoods are Mission Hills and Hillcrest. Very community-oriented.

Avoid renting in South Bay, Chula Vista, Lincoln Park area, as well as along the majority of University Ave.
