I wrote this in another thread, but thought I'd post it here, and maybe add to it:
Positive = on the seafront, you may get a great view. Closer to town, and therefore better for nights out in town/shopping. Bigger beds and rooms. (You'll need to get sheets for a bigger bed, but a single duvet will be ok.)
Negative = far from campus (but you will get used to the walk/be able to get the bus). You could get a rubbish view (my window looked into the courtyard). Pigeons will come into your room/kitchen if you leave the windows open when you are not there, I am not even joking. I shall also add that the amount of times the fire alarms go off is ridiculous, and the entire building has to be evacuated, so get used to that, lol.
I had an en-suite room, and our kitchen was massive. Only 6 of us sharing, all with our own bathrooms in my flat. Not all the flats are en-suite, but even the ones that are not are nice, lots more space than up on campus.
I had the same last year, wanted Rosser and got Alexandra Halls, but I really did love it in the end.
I personally thought it was a nice place to live. Any more questions just let me know
