<p>The shuttle is super convenient. Harvard Square is right on the Red Line and right in Cambridge which is great. The 2nd stop is a relatively short walk to the Common or right off a T stop at the Green Line and Newbury Street. </p>
<p>The commuter rail is a good option during the week and early before the shuttle runs. It’s only $3 which isn’t bad at all and totally worth it for some things (like Sunday morning dim sum runs).</p>
