Room needed ideally with a home owner

I’m 52 years of age, I’m from Cornwall where own my house still by the way, I’m up at 5am out the door by 6am home by 6-7pm so out all day.
I’m a projects manager for a design & build interior fit out company for high end apartments, we go from design intent to procurement, to final install and sign off, Which pretty much takes my time and energy, if you reading with interest then my next part but might be a deal breaker, I travel home to cornwall fortnightly so basically 2 x weekends a month I will need to stay in London, I have a car, I’m clean presentable, well mannered, polite with consideration, anyway thank you for reading this and if it spikes an interest then I’ll guess you’ll be in touch if not then good luck in your search.
