My husband and I just made a trip down and toured a number of what seemed like attractive options, spanning neighborhoods including Avenida Balboa, Costa del Este, and Clayton (among others).

They tend to attract big companies, hospitable systems, cool downtowns with good restaurants, lots of events, and are usually a 1-2 hour drive from a major metro and airport.
