Travel directions
IDDS is conveniently located in Central Square, Cambridge, at the corner of Massachusetts Avenue and Prospect Street, mid-way between Harvard and MIT, about a 20-minute walk to either. We have offices on the 8th and 9th floors of the 675 office building; the main office is on the 8th floor, which is also the location of the conference room.

Local Public transportation

Please See the Massachusetts Bay Transit Authority web site,, for buses from Allston, Brighton, Somerville, the Longwood Medical area, and other locations, which pass by Central Square, or have one end station there.
