Quiet.

Quiet efficient appliances. Well insulated walls and windows, including interior walls.  Proper underlayment and quality flooring that doesn't echo as bad that thin plastic laminate flooring.  A bit of space so people aren't always in each other's way.

Also, in a suburban setting, more expensive houses have bigger yards, creating a much quieter neighborhood.  We just moved from our first home in a shitty and cramped neighborhood to our dream neighborhood.  It's so much quieter.  Just generally less chaos all around.
