Internship abroad (England)

Hello Crossies,

I was hoping some of the English guys here could help me out. I am trying to get an internship in England for my 4th year of my current studies (Media / Web Development). The expenses are a pain in the ass though, as I have to pay for basically everything (the chances to get an allowance is close to 0%) Also, I will be staying there for a full school year, so it has to be a nice place! (Obviously, there is the possibility to stay at a colleague's place, but I want some more information)

Since I'll most probably have to pay for everything on my own, I can't afford a luxurious apartment in an expensive city. So I have some questions for you:

I heard for example Cambridge and London are great cities to scout for internships (and great cities in general to be staying for a longer period of time) , but they are very expensive, is this correct?

• What cities are relatively cheap when it comes to sleeping accommodations and general living supplies ?
  
• What cities would you recommend when it comes to my studies?
  
• Of course, I want to experience England as well, what cities are worth spending the majority of my year? (Also looking in the course of inviting friends over and seeing England in general)
