Hi (:
I am a current first year at Bath Spa, I live at Waterside Court and would recommend it as it's well priced, has en suites and is in a great location. Four out of my five fellow flatmates are based at Newton park and I think for them they really enjoy living off campus as everything is much easier to get to, however I'm sure living on campus has it's benefits as well, like JanuaryRose says you need to decide which you would prefer to travel for. Also consider that Newton Park campus is quite secluded, being on the outskirts of Bath. Hope that helps (:
