Proximity to Route 1 and the Beaches yet just far away to avoid the major traffic in the summer. There are work around routes off the route 1 corridor. In the Milton area it is somewhat unique in that it offers single, twins and apartment all with condo living. No maintenance. However, some will say pro, some will say con with the higher monthly fees... Cave Neck Road itself offers great neighborhoods and Paynters Mill is one. If no maintenance and amenity rich is important, PM is worth a look.
Best of Luck!
