What else do you like in and around Boston?
The metro area has more colleges and universities than I can remember, so there are lots and lots of intelligent people in their 20s and 30s.
If you like technology, there is a very strong "maker" community, with public workshops where you can build things or learn how to do so.
Tons of biotech and defense jobs in the area, if your husband is interested in either of those.
If you like nature, then there are gorgeous rocky coastlines just north of the city, hiking trails in the hills within the metro area, and major hiking and skiing areas within a few hours' drive.
If you like nightlife, Boston gets plenty of acts that play in larger cities, but here they often play in smaller venues, which can be nice. Small negative is that most places close up by 2 AM, but most people don't seem to mind that.
The city is fairly compact so it generally doesn't take too long to get to where you are going. Traffic is an issue during rush hour, however.
Boston has been welcoming immigrants for a long time so there are lots of adventurous restaurants to try if you are a foodie.
Easy trip to NYC by bus, train, or car if you want to venture a little further afield.
If you like sports, we've got the best teams.

You can relive your high school history class lessons by walking the Freedom Trail every time a relative or friend visits you for the first time.
😕 Ok, not so sure that one is a benefit.
