I love Cambridge. It is a very busy place but despite what you may have heard it is not too hard to maintain a decent work-life balance, as long as you keep up with all of your work and try not to fall behind. I like the College system as it allows you to meet more people outside of your subject, for example when you go for formals or swaps. Everything is very central and most colleges only need a short walk to get into town. The course itself (engineering) covers a lot of ground but is interesting and well taught.
