We are two sisters who travel together frequently and have time to travel mid October 2011. We are the museum/history site seeing type people as opposed to adventure type travelers. We just can't get our heads around Boston. What area is the best to stay in? Our criteria is usually safe, clean, close to public transit, and affordable ($200/night or less). We are also having trouble figuring out what to see, the Freedom trail looks promising, but what else?
