I saw them before they were campus housing. If they're the brownstones I think - they're nice, real nice. They probably changed the insides though since when I last saw that specific area where housing is awhile back (I have relatives who lived very close to there). I remembered the street when I saw it on the housing form, but I can't remember it for the life of me now.
They're expensive as hell though, like a grand a month if I remember from their housing forms. It's a very costly area to live, so it'll probably save you a ton of hassle though. The price is fair, but far from a discount.
If you don't know the Brooklyn Heights area, and can't go apartment hunting in person, it's probably not a bad idea to get housing through the school. It's in a great area, though. Sorry I can't be of help on the interior though. Best of luck!
Oh, btw some law schools have off-campus apartment listings for students (that aren't through the school). You might want to request that too from admissions or residence life. If I hadn't registered for housing through the school at SJU, I would have requested that. I sent in my housing deposit today.
