Room wanted

Hello,
​I am a professional lady working as a self-employed Bookkeeper, currently looking for a peaceful and respectful living environment. I am seeking a single room /box room with a budget of £500 per month, all inclusive.
​I value a quiet and orderly home. Given my background in bookkeeping and household management, I am naturally organized, clean, and very attentive to property care. I lead a very quiet life, I do not smoke, and I do not bring any guests home.
​I am looking for a female or mixed household where mutual respect and a calm atmosphere are prioritized. I am open to both short-term and long-term arrangements.
​If you have a room that matches this profile, I would be very happy to discuss it further.
*I have rather new-renovated house-stuff etc. If even 1 person smokes in the house please do not contact me.
​Best regards,
*if you have an elderly and not require anything ,just someone being at home at night time ,this will work too.*please get in touch.
