Quick Tips:
Accomodations vary widely. Be careful in choosing location as neigborhood character can change quickly. Cambridge can often be a lower cost, equal quality alternative while providing great views.
Boston has all the crime problems of much larger cities. Be alert and wary. Do not assume that quiet residential neighborhoods are safe. The criminals may not live there, but they do know the way.
Best Way To Get Around:
Walking and public transportation are all you should need. The best way into Boston from the airport is the water taxi. It will take you directly to the Boston Harbor Hotel. From there, you can either walk or take a subway to almost anywhere you want to go. Taxis are also readily available. There are no taxi stands in Boston, so wave, whistle or do whatever you have to do to get their attention. It's also easy to get taxis in front of any hotel. The Boston subway system (the T) is easy to follow and very efficient. The oldest in the country and second oldest in the world (following only London) it deserves at least one ride. What ever you do, do NOT try to drive in Boston. Boston drivers have a reputation of aggressiveness which is somewhat deserved (although I prefer to consider it assertiveness). Boston roads used to be cow paths. There is no neat pattern like other cities. That means there are ambiguous intersections which confuse those new to town just enough that locals push their way in to keep on schedule. No offense intended. Actually, we consider ourselves to be defensive drivers.
