I'm a fresher here (been here for 3 weeks) and I really love it. I live in Goodricke college which is basically this brand new complex which is totally awesome, even if it's a 20 minute walk to campus.
Depending on where you look, York Uni is a top 10 (Sunday Times Uni guide) university, which is also rated in the top 80 in the world. You could do a LOT worse.
