Southampton is a great university for accounting and finance. The school of Business that it falls under is quite large and very well equiped. We have several modules that have been aredited and so give you exemptions from some of the professional exams you may want to take for your career. As a City, Southampton is not too busy but still well connected with buses (including a system designed around the University of Southampton) as well as two major train stations both about 1hr 20mins away from London Waterloo. About 20% of Southampton's population is comprised of students so the city is well tailored to students with an array of clubs and bars, which are varied in intesity (so there's a choice depending on how you're feeling). Socially, people are quite frienly in Southampton and,as a student, there are many society and social events you can get involved with throughout the year.
I hope this information has been useful to you. Please do consier all of your options carefully and do lots of research (including maybe going to see the universities) before making any final decisions
Best of luck
