I'm looking for flat or large double bedroom ...

I'm looking for flat or large double bedroom with en-suite in Leamington or Warwick, with good bus route. I work at school in Leamington off the Parade.
I would prefer on suite as i have been sharing for many years and its not been so easy and would like something self contained. I require something clean and quiet, these are most important for me and respectful. In return il stay for many years. Please be honest in your response. let me know if you have something suitable. Please note this is not for myself but close female friend im helping to relocate
