Short Term Let only in Lovely Artists Home

This is a bright large double room with desk in my gorgeous 5 bedroomed house in Finchley. The room is my son's who is at uni and will be returning home for the holidays so it is only available until 13th December and then from January 12th for 12 weeks maximum. I am only looking to do short lets for this room.
This lovely room shares a bathroom with my adorable lodger who is here doing an MA at UCL until June. My bedroom and bathroom are on a different floor. I'm always told my house has a welcoming and warm vibe. I've recently had a new kitchen and it's a relaxed and pleasant space to sit and eat, as is the lounge and dining room.
I'd ideally like a uni based mature or post graduate student or an office based worker but definitely not someone working from home or based from here in the daytime. I am servant to an elderly and much adored cat called Millie. We are an all female house and would prefer another female. References are essential.
