Great that the college offers accommodation for all years of your degree- this isn't common amongst Oxford colleges so definitely a bonus. Also very well-located - central and largely quiet. However, the accommodation is hugely expensive for what it is. Especially when so many of the rooms are outdated. In my final year I got back pain from the poor mattresses and I would wake up with paint on my forehead as the paint job was so old that it would flake off. Freshers would make a lot of noise which made it difficult to concentrate as a final year student, but porters took care of this the vast majority of times. Note that if you stay in the GAB they cannot do this for you.
