Room In House Or own Flat. Anything Considered.

I lived in London all my adult life and having sold a family property (so solvent), I'm looking for somewhere in Lancing or surrounding areas as I have lived here since November last year. Young at heart, mature gent, former London Tour Guide and Professional Musician. I'm an outdoors type who is a keen Cyclist and Motorcyclist so not at home much. Older but young at heart and certainly, outgoing and sociable but very mindful of other people's need for privacy and space. I like to cook but will leave kitchen clean and tidy immediately afterwards.....I'm house-trained.
A verbal or written reference is available from my current live-in landlord, who due to needing to care for a family member now needs my current accommodation.
Thanks for considering me,
Charlie.
