The easiest way to reach the lab is by share ride or public transit (Bus #66, #86, or Harvard Shuttle from Harvard Square T station). Unfortunately, the surface lots behind 150 and 114 Western Avenue are not open to the public; here are the options for parking nearby:
A limited number of free visitor parking passes are available for the HBS Parking Lot near Spangler Hall (across the street from the Science and Engineering Complex). These parking passes last all day, but you will need to email firstname.lastname@example.org at least 24 hours in advance to request one.
Daily parking permits in other Harvard lots are available for purchase through Harvard parking.
There is metered parking at 2 Hauge Street (behind 114 Western) and between 125 and 127 Western Avenue for $2/hour. These meters take credit/debit cards, as well as cash. The maximum time allowed is 4 hours.
There is additional metered parking available on Ivy Lane for $1.25 for 2 hours. These meters take credit/debit cards, as well as cash. The maximum time allowed is 2 hours.
Once you arrive at the Science and Engineering Complex (150 Western Avenue), take an elevator to the sixth floor. Suite 6.220 is located to the left. Email, call, or text the person with whom you are meeting to ask them to let you in.
