Congratulations on the admission to Hopkins!

If it's for undergraduate, there's plenty of on campus housing and the neighborhood there is very walkable as well.

If your kid is at Peabody, they'll be living in Mount Vernon.

Mount Vernon is central for walking, public transportation, and biking. The Inner Harbor isn't what it used to be, but it's a nice walk from Rash Field to Fells Point. You can also take the commuter boats across the harbor. Check out the American Visionary Arts Museum. Have a wonderful visit!
