4 bedroom semi detached house

I am a 40 year old female. I own and live in a 4 bedroom semi detached house on a quiet street in Towcester. I live with my son who is 6 years old, however he spends every other week (including the weekend) with his father. I am a nurse and work 12 hour shifts on these weekends which provides sensible freedom for the applicant. On the weekends I have my son I mainly travel with him and also away from Friday to Sunday. I have a small garden with a covered seating area so happy if someone is a smoker however only permitted outside and not in the house. This is only cigarettes. Preferred non smoker as preference. I have a drive way which comfortably fits two vehicles, one of which is my own. I have a converted garage with plenty of storage cupboards if needed and a TV which could be used as a second alternative living room if needed. I have a downstairs toilet, and two bathrooms. The spare room is a double currently with a bed (although it was a cheap buy) bed side tables, a desk and a vanity table. These can be removed if needed. The main bathroom would be used as the other is my en-suite. The 4th bedroom is used as dressing room and happy for some wardrobe space to be used if needed. The house is within walking distance to the high street (6 minutes) and a 2 minute walk to a local one stop. I am preferably looking for a professional female. As it is my home I expect the person to clean up after themselves and respect the property ie no parties. I do have a dining table and happy for this to be used for a few friends when I am away at the weekends. I do not have any pets.
