Spacious room or ensuite wanted

Hi, I’m 18 and looking for a spacious, private room. Ensuite or something with a bit more privacy would be ideal.
I’m clean, quiet and keep to myself. I’m looking for a calm household — not a party house or somewhere too busy.
I’m currently focusing on my next steps with education/work, so I keep things structured and low-key day to day.
I have stable income through Universal Credit and PIP, so rent is always covered and paid on time.
Budget is £400–£500 per month.
Ideally looking for something longer-term and would be happy to stay for at least a year.
I’m ready to move soon and can arrange a viewing when needed.
