We highly recommend the houseboat life as a lodging option when visiting Boston. Charlestown is a beautiful, historical area. The Navy Pier itself is a super, safe area - lots of walking and outdoor areas to take in the scenery. The Water Taxi is a great transportation option to and from the airport - it dropped us off right at Pier 8 where the houseboat is - plus you're on the water seeing the Boston skyline = bonus! If in doubt, don't hesitate, hit the button to secure your spot on the houseboat - you won't regret it!!
