Living cost first of all is very good. Better than the rest of the country ! As for international students there are lots here from Canada greece Cyprus spain France everywhere. They come for the 5 year course too.
People aren't overly friendly I have found, perhaps because there isn't such a big drinking or party vibe, but I made friends in first year and was quite happy once I settled in.
Im sure you will like it, the course is interesting, the campus is realy cute and pretty and there's loss of nice accomodations to choose from, plus a big tesco, asda, and other privately owned supermarkets near by. The food is amazing.
