We had a fantastic overnight stay on Karen and John's houseboat! Karen and John were wonderful and attentive hosts and suggested many places within walking distance. The houseboat itself was very clean and rocked us to sleep that night. And the location is fabulous,. Right next to the historic Charlestown Navy Yard. Definitely a spot we will revisit! In fact I'm going back in October for an overnight with my girlfriends ... can't wait!!
