Intern starting Sept 7th, need a room near Towcest

Starting a year-long internship on 7th September and need to find somewhere before then. Budget's £500-600ish a month, bills included would be great. I'm out at work most weekdays so not around much to be a nuisance, don't smoke, no pets. Genuinely don't mind if it's Towcester itself or Northampton, whichever has better options honestly. Room in a shared house or a small flat both work fine, I'm not fussy about the setup.
