Hi there
To add to my colleague Erica's reply, I have lived both on and off campus and so can provide some insight on both!
I definitely recommend a few criteria to look out for when choosing on campus accommodation. When I was applying to uni, I was personally quite keen to have an en-suite so I put emphasis on this. For some people this is quite important but for others not so much, so this one's more of a personal decision.
Distance to lecture buildings / the library / campus facilities like the post office and co-op is another thing to consider. Halls such as Swanborough and East Slope are very central and you could only be a few mins away from your lectures which is very convenient. The central location does mean however that it'd be a bit more noisy here than say Northfield, which is about a 5-10 min walk away from lecture buildings but it does have a calmer atmosphere from my experience (this is where I lived in 1st year) which can make it a bit easier to concentrate on studies for example. Stanmer Court is also a great choice as it's right next to the Falmer train station and bus stop, so going to town is very easy and convenient from here. Brighthelm is another great option as you're provided with your own laundry facilities and these residences are more like traditional houses rather than halls, which some people really like. People do usually enjoy their time at uni regardless of which accommodation they stay in, but different residences do have their own slight perks so this is definitely something to look out for.
Finally with regards to on campus accommodation, price is of course a very key factor in the decision making process as well. The prices do vary across the different options and understandably the en-suite and more newly developed options do tend to be more expensive so this is something to be conscious of as well.
Most of the above also apply to looking for housing off campus as well, regarding the points on price and distance to uni / local supermarkets. Public transport links are something to look out for too when living off campus. I'm happy to elaborate on this further but I assume you're talking about on campus accommodation so wanted to focus more on that.
Do correct me if I'm wrong though!
I hope this response has helped but if you have any further queries, please don't hesitate to get in touch.
