It was cold and damp when we arrived at the Green Turtle Floating Bed and Breakfast in the Charlestown Navy Yard in early November. Not exactly high tourist season around Boston Harbor, but we live here, a short commute outside the city; we've already toured Old Ironsides. Taking advantage of one night with no responsibilities – while our mother-in-law stayed at our house with the kids and the dog – would have been heavenly in a full-on Nor'easter.

The number one-ranked Boston bed-and-breakfast on TripAdvisor, the original Green Turtle accommodations have little in the way of old Boston charm, at least from the outside. Situated out at the end of a floating dock, the two-room box looks like a double-wide spruced up for a small suburban lot with window planters and an olive paint job.

Step inside, however, and you may not want to leave. The view from the tall, plush bed, which dominates the room, is truly extraordinary, with the Boston skyline twinkling behind a slow parade of private boats, dinner cruises, and huge container ships navigating the harbor. The gentle sway of the room may lull you to sleep before you even decide on dinner.

Proprietors Karen and Jon are having so much fun running their B&B, they recently purchased two yachts, each with two handsome queen staterooms, which occupy the slips adjacent to the original boat (and the one they live on). The yachts are Jon's new pride and joy, and he whisked us aboard for a look around while the current guests were out.

We stopped at the nearby Navy Yard Bistro for a starter before heading over to Boston's North End for our dinner reservation. Even after loading up on dessert, we were compelled to stop in one of the neighborhood's classic Old World Italian delis, where the meats hung from the ceiling and the cheeses mingled into one very pungent aroma. Despite the chill, we skipped the cab and walked back to the Navy Yard across the short Charlestown Bridge. The wide red stripe painted down the center of the walkway marked the route as part of Boston's famous Freedom Trail. On our way back to our warm floating room, we felt, in fact, liberated.
