Mon-Fri Teddington or nearby for professional male

I’m a civil servant, based in Whitehall but seconded to National Physical Laboratory in Teddington until the end of March. I’m married, living in Cambridge, with two grown-up sons who live and work in London. Currently staying in local hotels during the week , but would prefer to stay somewhere where I can leave some clothes over the weekend and prepare my own food. Most weeks would only need Mon-Thu and would be out from early morning to early evening each day.
