The Dixon Mills project is a very nice complex. I know several people who bought there and are really happy. The building has unique lofty units and desirable amenities like a large fitness center and concierge.
As far as safety I recommend calling the Jersey City Police Department for a crime report in the area. They are best people to answer that question. Here is their information.
Please let me know if you have any additional questions.
