A room 1-3 days per week

I am a psychotherapist, looking for accommodation in the Angel, Kings Cross, City Road areas mainly, but I realise that there are some beautiful properties a little further afield which I would be more than willing to consider. Safety, cleanliness and accessibility are my main concerns, I have been living in my present apartment for 15 years but the landlord wants the accommodation back within the next month or two.. However, I can move straight away if needed. I will pay extra for an en-suite and some outside space, but neither are deal breakers. I have family and property in York and sometimes spend a couple of weeks or a long weekends there.
I mainly work in the City (St Barts) and Marlebone areas. I'm not a party animal but enjoy going out for meals or to the pub occasionally! Reading, cooking, fitness, travel and Art are my main areas of interest. I am quiet but chatty!
Some might say that I'm fun to be with and a good listener. I have shared with both male and female.. either is good. Someone wanting to rent out a cosy little spare room a couple of nights a week would be ideal. I really don't need the use of a kitchen, but a kettle would be nice so I could make a cuppa! I can sit and chat for as much or as least as you want..
I can pay 6/12 months rent in advance for the right property and I can provide excellent references.
