Advices on the selection of exchange student university

I am studying at Seoul National University in South Korea and having trouble with choosing university in UK for the exchange student.
I've been thinking between University of Bristol, University of Liverpool, University of Leeds, University of Glasgow, and University of Sussex.
I'm going to apply to the department of Bioveterinary Science for the Liverpool and Biological Sciences or Biomedical Sciences for the rest.
Actually, I had studied for 3 weeks in UCL this summer so I wanna go to other city in UK for the exchange student.
I'll stay for spring semester (January ~ May) and have plans to go to many cities in UK such as Edinburgh (especially Highland cuz I've been to Edinburgh for the day trip this summer), Newcastle, Glasgow, York, Cardiff, Manchester, and Canterbury.
During the Easter vacation, I wanna go traveling to other countries in Europe (Switzerland Chamonix/Montreux, France Nice/Paris) and after the semester ends, I'm planning to go to Eastern Europe (Czech Republic, Austria, Germany, Hungary).
Could you recommend me one that meets the standards below between those universities?
- has fancy places to enjoy (like pubs and restaurants)
- beautiful campus
- famous for its academic results
- convenient and cheap to move to other cities in the UK and Europe
- good public safety
- student-friendly
I have not enough information to choose between them so I appreciate your help now XD
