I'm considering the above places since they are pretty close to Aston Uni. But I wanted to know more about them before I make a decision. Especially if they are appropriate for a post-grad student.
Contrary to the above, I don't think there is anything wrong with Heights. I stayed there two years back and it was perfectly fine. However, you might want to consider Cosmopolitan (new this year) which is across the road from heights or indeed the new university accommodation.
