mapofMAPAWe’re in the basement of the First Church in Cambridge, Congregational, at 11 Garden St, corner of Mason.  The large stone church is the last building before the Sheraton Commander hotel, which has a large red neon sign at night.
Facing the church from Garden St, enter the parish hall on the right, along a brick walkway.  Once inside the building, come downstairs and you will see signs to Peace Action.   
By T, use the Church St exit from Harvard Square T stop.  When you reach street level walk right across Church St, and after a short block bear L onto Garden St at an old grave yard.  Cross Mason St which is your second left on Garden. 
By car, there are parking meters on Garden St and some around the Cambridge Common, which must be fed from 8am to 8pm.  Maximum time is 2 hours which costs you $2.50 in quarters or by app.  We also sometimes have a parking permit available which you can reserve, run in and pick up; it entitles you to park on certain streets in the area.
By bike, there are racks to the left of the brick walkway.
