Thanks. I think city centre would be OK as well. I'm not familiar with Nottingham and I'm basing this on using Google Maps, it looks like a nice (architecturally) and upbeat area. I get very depressed living in secluded areas, I like to hear a little noise and feel like getting a carton of milk is no big deal hehe otherwise I feel trapped. I guess city centre could be OK.
I was thinking a bit futher out lol. A lot depends on what you are looking at spending and if you would be willing to do a flat (or house) share (i've been seeing quite of few of these posted at work.) A lot of the student areas are going to give you the noise and non-seculded feeling. TBH I don't find much in Nottingham to be secluded, I may complain about the buses, but we live on the edge of Nottingham so it's to be expected.
i'm not sure what they have in the way of city centre flats, but take a look at this link:
http://www.netletnottingham.co.uk/search.asp it is for an organisation called unipol that does a lot of student lets. There are some studios in a place called trinity square which is across from the major shopping centre in town and really close to Nottingham Trent University. They are run by a company called Derwent Living and have studios along with en-suites, but the contracts don't start until the 25th...
Another couple of areas to look at are Lenton and the Arboretum; they are outside the city centre, but have good bus connections in, and are big student areas so you'll not have to worry about it being too quiet. Stay away from The Meadows or St. Anns.
Any questions let me know.
