Under those criteria, no.
The only green spaces at Notts are on the actual campus itself, so you'd be trading the countryside for what is effectively a park on a hill. The campus is pretty much town (if not city) centre and it is really rather grey. The Jubilee campus looks like something out of a low-budget 1970s dystopian scifi movie. I would absolutely urge you to visit before making any decision.
Nottingham is very strong academically, and also extremely good for sports. I personally think the going-out thing is overstated. People go on about the legendary nights out, but these things are limited by your budget and you also have to take into account how unbelievably dodgy Nottingham is.
You'd get an excellent degree and have a great time socially - but if you want green spaces, I don't really think its the one.
