BPP University? Watch
The only other BPP site I've visited is the Holborn Law School which was even more impressive than the Leeds one! If you go into the Waterloo Law School someone should be happy to show you around (they did when I first applied) though emailing someone in advance might be advisable
The Waterloo Law School is right opposite some of Kings College London's facilities so is in a reasonably nice area, however you're also only a few minutes away from the west end etc and (I think) you can use Holborns facilities too if you'd like!
I get slightly defensive/irate when it comes to BPP's reputation, I've undertaken a few mini pupillages at some very well known chambers and a number of barristers at them have spoken very highly of BPP and explained that though it is only a young degree because the tutors have previously been teaching the GDL/BPTC/LPC and are mostly solicitors and barristers they see it as very respectable. Obviously you will still need to be getting good grades to succeed in the competitive world of Law and the BPP name isn't going to help you out that much if you scrape through your degree. A number of people on this site seem to really dislike it and seem to pretty much enjoy telling people not to go. I wouldn't listen to them though, as I've said I've spoken to Legal Professionals who are happy with the BPP degree,I'm a current student and I love studying here so my case should hopefully be pretty strong regarding BPP
If you want to know any more it's probably best to get in touch with BPP themselves!
