Single study or shared study?

Planning to go to Nottingham Uni this year, and am deliberating between single study and a shared study accommodation...

From the Nottingham website: https://www.nottingham.ac.uk/accommodation/accommodationoptions/cateredhalls/university-park/room-types.aspx
---Single study is your own bedroom with separate study area shared by two people with two sets of study furniture
communal bathroom shared with no more than five others
---Fees: £4,688.74

Single Study:
---your own bedroom with single bed and study area (not all single studies have sinks)
---communal bathroom shared with no more than five others
Fees: £5,251.56

I'm not sure what to do, because I'd like my own space, of course, but if it's£70 a week cheaper, it seems like a great saving. I'm not that bothered about a shared study area either, as I could go to the library or just study in my room if I wanted. But then there's the problem of if my roommate is nuts :/

Any advice? Opinions?
Thanks!
