I can't speak about the specifics of exchanges, but it's a 13 minute bus to Coventry train station, and from there it's an 18 minute train to Birmingham airport or a 1h10m-ish train to London for the Eurostar/other airports, so it's well located for travelling around.
Campus unis won't be for everyone, but I find it works quite well. Everything is very central and close together so it's really convenient for studying, and there are so many societies/sports clubs/events/club nights that there's always something going on on campus. It's also really easy to get to Leamington/Coventry/Birmingham (and even London now with the more direct trains) so plenty of opportunities for city life too.
