LSE any good?

Hi there, I plan on doing my first solo trip to London this September and after some digging I was thinking about booking a room for one week in LSE. Any experience with Passfield or Bankside? I know it’s a student dorm during most months so by no means I’m expecting high end hotel suite but is it worth it or will I regret it in no time? Premier Inn prices are a bit too steep but not out of reach, I would rather spend the money on attractions rather than room.
