We did a visit to Boston to see the exact same four schools with my daughter. We also had visited schools in New York, and my daughter had not liked NYU, so we were not surprised that she also did not like BU, but we were glad that we did the tour. She really liked Northeastern and BC, and is now a freshman at BC.
I’ll echo some of the recs from others: Freedom Trail, which will go right past Boston Commons which is a beautiful park. Faneuil Hall is touristy but has shopping. For good shopping, coffee shops, gelato, I’d highly recommend Newbury Street. I think my daughter heads there about every weekend.
Definitely go to the North End for great Italian Food and cannolis. I’d recommend Prezza (get the ravioli appetizer with the egg inside) and then Mikes Pastry afterward.
I’m assuming your spring break is in March, so you’ll likely be too late, but if in very early March, I’d recommend going to a BC mens hockey game. The team is ranked #1 in the country and the games are super fun. But, I think the season ends in early March.
We’ve stayed in the Hotel Commonwealth a couple of times, and I’d recommend it. It’s walking distance to Northeastern, and Newbury Street, and is right next to a T Station.
