Ehi there!
I have been visiting the campus and it is truly great; even though it is really in the middle of nowhere, it has everything in it (shops, restaurants, sport centre, ect) and the environment is energetic and intellectualy stimulating. Around the campus is full of green open spaces and I just love it - but depends on your tastes.
I have seen the small towns around the university: Coventry is a very sad place, but Leminghton and Warwick are very pretty and lively. I believe that I will not stay in the University accomodations and I will look for something cheaper. Leminghton is very well connected to the univerisity and Coventry too. From Warwick, there is actually only a bus (or maybe two) service.
Maybe I'll see you there next year! Let's keep in touch =D
