Professional museum worker seeking Mon-Fri room

I'm seeking a room from 3rd August, for an initial period of 1-3 months, but likely to be longer-term; I'm starting a new role in August so will need to see how the work pattern pans out.

I used to live in London but now live in Wiltshire with my husband and lovely cat. I need a Mon-Fri room, and ideal areas are Barnes (where I used to live), Hammersmith or Belsize Park.

I'm 43, quiet, polite but social in the right setting! I'm most likely to be working in the evenings or going to the theatre/cinema, but would like to be able to have access to a kitchen to cook some healthy meals.

I also love running, yoga, swimming, being active, nature and wildlife. I run a book club and love the cinema.

I adore cats so bonus points if you have any!
