It depends on how much you want it. If you're really not bothered about a shared bathroom then I wouldn't bother wasting about an extra grand in a accommodation fees when you need all the money you can get at uni. But for me, I really wanted and do have an ensuite. The thought of sharing a bathroom with total strangers with no idea how hygenic they are scared me enough to get an ensuite room this year at uni. While I pay extra, I very much appreciate having it there especially like others have said when you're ill/on your period.
