Follow the Massachusetts Turnpike, Route 90 East. After you go through the tolls just outside of Boston, you continue on 90 east to exit 18 (Exit on Left). As you go through the tollbooths stay to your left following the signs for Brighton/Allston. This will put you onto Cambridge Street. Drive over two hills. At the bottom of the second hill at the lights (this is app. 1.2 miles from toll booth) turn left onto Harvard Avenue. Follow Harvard approximately 1.3 miles to Alton Place. Along the way you will go through three major intersections, the second two will have trolley tracks. The last of the three is Beacon St. (this is Coolidge Corner). After you cross Beacon Street continue straight on Harvard Street; take your third left onto Alton Place. Take your first left onto Littell Road. The Coolidge Corner Guest House is the fourth house on the right, # 17-19.
