I love living in Leicester! It is amazing.... i come from just outside London myself and used to use the night bus. I don't care anymore, id rather get a cab! And with enough peoples its cheap enough anyways! From town to halls with 4 people costs about £1.50 a head, from the uni to halls you can get it at a £1.20 if you dont take the first taxi!
The campus itself is lovely, very pretty as louise said, the halls are lovely, the people are friendly and tis great!
I love living in Leicester but i suppose it depends on the person! Is it possible you could visit the two unis and see which you prefer? It may be good if you could!
