From the West:

Take the Mass Pike East to exit 17, at Newton / Watertown.
At the end of the exit ramp, at the stop sign, merge left into one of the far two left lanes.
The road will continue left and take you over the Mass Pike.
On the bridge, merge over to the right lane.
Go straight and bear slightly right through the set of lights. This is Centre Street.
Centre Street eventually becomes Galen Street.
Galen Street ends at a set of lights with a five-street intersection.
Bear right onto North Beacon Street.
The road will fork quickly. Bear left onto Arsenal Street.
On the right-hand side, you will pass a very large brick building on your right, with large windows. This is the beginning of the Arsenal Complex.
Continue down Arsenal Street.
At the next set of lights, take a right (across from Roma Tile). This is Talcott Avenue.
Continue on Talcott to the stop sign (after the first block of buildings). Take a right.
You may park in the parking garage straight ahead. Or, follow the road as it bends to the right, around the parking garage.
At the DO NOT ENTER signs, take a left.
Take another left into the outside parking lot.
After parking, walk across the road to building #311.
