Hi-
It sounds like it'd be a good match for you.
Kenilworth is a good area - Working class people, friendly atmosphere.
The commute to Manhattan shouldn't be bad at all - There's no train station in Kenilworth, but there is one in Roselle Park (the next town over) as well as in Linden (a few towns over - not far), and those will bring you into Manhattan.
(If your husband wants to look into different commutes into the city, he can check out
www.njtransit.com, as well as
www.panynj.com.) The commute is not difficult at all. Your best bet would be to drop him off at the train station in the morning - He'd take the train to NY Penn Station & from there take a train that goes directly to Grand Central.
Hope this helps!
Allison
