Harbor Vista's Unit 101 is quiet for two reasons. One, it is on a street with no outlet. So there is no through traffc causing noise and chaos. Secondly, the unit is sound proof due to its concrete inner walls and ceilings.
Another interesting footnote is
that out of every window and door and there are 10 of them, there
is a minimum 'clear' sight line of 500 + feet. Truly unique for
the New Jersey seashore.
