Hi Slimpy
Boston is a town my wife and I know pretty well. In the last 10 years we have used it as our first night stopover before renting a car and touring New England each Autumn. In addition we have spent two vacations , each of a week, just in Boston itself. The last one was last November
Not sure what your interests are but there is alot to do in a week in Boston. There are lots of museums, the best being the MFA and the Isabella Stewart Museum. Also a visit to the incredible Mapparium in the Christian Science Building is worth it. Built in 1935 I think, you can walk inside the glass globe and see the world as it was then.
Boston is a smallish city and relatively flat , so it is easy to get around. Think you will find the Freedom Trail worth it.Lots of stops on the way where you can have a beer and people watch !
Also a day spent at the JFK Memorial Library on the banks of the Charles river is a must we think as is a visit and tour around the Campus of Harvard .
Last November,we took a day and caught the Metro to the homes of John Adams, the second President of the U.S. That was good and well worth doing.
Lots of good shops if that is your thing , especially along Newbury Street and alot going on each day and evening around the area of Faneuil Hall.
Finally Boston is full of very good restaurants and bars. Especially in North End where there are alot of very good Italian restaurants. Our particular favourite is Mama Maria .If you like fish , there is Legal Seafoods overlooking the Harbour and Ostra. Both recommended. Also it would be good to eat at Union Oyster House which I believe is the oldest restaurant in the U.S. I think JFK and Bobby Kennedy reguarly dined there when they were young
May we also recommend XV Beacon hotel which is in the heart of the city and a 5 minute walk from Boston Common. From the hotel, you can walk the historic Beacon Hill district and have a peek at some lovely old houses owned by very wealthy people. Believe one of them is owned by John Kerrys missus....heiress to the Heinz Empire. There are lots of big flashy hotels in Beantown but if you fancy something small and quiet and classy, XV Beacon would be good. If you push you can get good deals out of Season especially for the slightly smaller "Classic " rooms which are fine.
I'm sure there are lots of people on here who know more about Boston than we do but I think that's enough to be going on with ! Hope it helps to make your mind up
