The facilities, the location (china town and Boston in general - a 5 min walk to the ocean). The admissions staff, faculty and students went out of their way to make you feel welcome and comfortable. The food and free Tufts University toothbrushes they gave us were a nice touch too!
What impressed you negatively?
had to pay 24 bucks to park...but that's to be expected - I was so jazzed about the school that I didn't even care.
What did you wish you had known ahead of time?
that the school accepts 85% of all interviewies...would have put me at rest a bit more.
