Manchester is awesome
Admittedly im beyond student housing now and live in a nice new apartment near the section they call the Northern Quarter, but even then the city itself is just great!
Personally I don't like the very studenty areas as hang outs, though they are cheaper of course, when you're there i'd mix it up a bit and occasionally get yourself to the nice bars in the Northern Quarter (£3 a pint though) and Deansgate.
You get some really good bands gigging in the unions 3 venues (Academy 1/2/3) and the union itself is pretty good too.
I spent my student years in a place called Stafford near Stoke-On-Trent and feel safer out at night in most places than I ever did in Stafford. In fact my only "confrontations" have ever happened in stafford.
Sure there are loads of chavs about, but most of em are just "proper" mancunians

just look to Ian Brown for an example. Rough as hell, but most of em are fine people.
Manchester is no London, nor would I want it to be. Its a compact and reasonably small city with lots of heritage and history to explore, some good museums, enough nice bars and pubs to just be able to hang out for a whole day if you wish and so many clubs that if thats your scene you will nearly always have somewhere new to go for many many months. The fact its much cheaper on the whole than many major cities is nice too

Lots of shopping as well of course.
Last year I lived in a 2 bed apartment that was brand new, v nice etc and was £750 a month. The housemate I had has just found a far smaller and less well equipped place in Epsom and hes going to be paying £1200 a month!
What department are you coming to at Manchester? Comp Sci or something else? If its comp sci, make sure you make the most of the fact we have a lot of people lecturing here who had a large hand in forming the subject area they teach (Steve Furber comes to mind).
I hope you enjoy the city as much as I do
