Port Aquia is a splendid townhome community, ideal for commuters. It's located off Rt. 1, but in less than a minute, you can be on I-95, and in minutes hit Quantico. Some of these terrific, three-level townhouses have a garage. Many of them have four bedrooms, three and a half bathrooms, a spacious kitchen, a deck, or a fenced-in backyard.
