Congratulations on your acceptance!
I'm Molly, I'm in my second year of the program with Jen.
For those of you that are coming from out of state I highly recommend having a car. Chances are you will be assigned to clinical sites that won't be accessible by the T or very challenging to get to at 6:30 am. The T is great when you have clinicals in Boston, as there won't be parking. I only had two clinicals in Boston, most of them have been out in the suburbs. The shuttle is also very limited, especially in the summer.
As far as housing goes I recommend looking at Waltham. It borders right on Weston and the rent is a lot cheaper than living in Boston. There's some public transportation (bus lines and commuter rail) and having a car there is pretty easy. Newton has some affordable apartments, but it's generally expensive. Finding an apartment in the suburbs will be a lot easier than finding one in the city.
