Directions by plane:

At Logan, shuttle buses run regularly from each of the airline terminals to the MBTA Blue line. Take the inbound train to Government Center. Get off and follow the signs to the Green line. From there take any eastbound train to Park Street and change to the Red Line. Take a train in the Braintree direction. Get off at South Staion. Phew! Follow the MBTA directions from there. Otherwise, hire a taxi.
