Worth it? Absolutely. Just know what you're getting into (cost of living being the primary consideration here).

Few things:

1. Forget Weehawken (with apologies to the Weehawken boosters in this sub). It's not what you're looking for in terms of vibe or convenience (The Pt. Authority bus station is the 10th circle of Hell).
2. JC is BIG. So you'll really want to limit your apt search to the areas within a short walk to the PATH. JC Heights is only a mile or two from DTJC, but in terms of commute/accessibility to NYC, it might as well be in another county (i.e., 10-15 mins vs 45-60 mins).
3. The "Hoboken Bro Vibe" is both real and overblown. Yes, the throngs of douchey bros (and the suburban white girls who love them) overrun Washington St. on weekends, but Uptown/West Side areas of Hoboken are quiet (and Hoboken really is lovely when it's not under water).
4. Bring good shoes. For lanternfly stompin'.
