Aldershot is a large garrison town, about 4 miles away is Farborough either places should be OK for getting a room in a shared house. a double room would probably be somewhere in the region of Â£100 to Â£140 per week plus a share of the bills. be aware that you are moving to a very expensive area with house prices starting at about Â£200K for a starter home.
Guildford is the home of the University of Surrey and has a large student population, Canal Drifter is the man for you he is local at Mytchett, get him to send a local paper. Also Ash, Ash Vale, Frimley, Camberley. As previously said this is the Surrey/Hampshire border and is not cheap. In fact Aldershot is about the cheapest housing in the area.
