I've been accepted by the University of Surrey for Psychology in 2016! (I deferred a year)
When I went on a campus tour I was really impressed by the psychology facilities - there are specialist areas of cognitive, development etc. The course is also designed to increase your employment prospects with a sandwich year, which is great for actual working experience in the field rather than just having the academics of it.
For the accommodation I would say the on-campus environment is really great for socialising, and is also conveniently near everything you'd ever need. (Town shops about 10 mins walk away) The negatives of the accommodation I would say is if you're wanting Band D, which is ensuite, as it is very small for the price. The Band C houses actually seem like a better deal, as they are more spacious rooms and have a very communal feel.
Surrey itself seems like a really nice town too, the clubs are a little lacking but with a few drinks I think you can turn anyplace around :')
