Looking to start a flatshare

I'm mainly interested in starting a flat share with one or two like-minded individuals. It would be nice to find a set-up where there is a balance between personal space and having a living room that we could enjoy together from time to time, giving the space a homely feel.
Here's a bit about myself: I am 38 (M, gay) and work as an academic (postdoctoral research fellow at King's College London as of June) in philosophy. I'm currently based in Berlin but I did my studies in London and lived there for about 8 years. I'll be coming with my cat, a very loving old feline. Otherwise, I love going to the theatre and I'm generally quite a curious person who can get into a lot of new hobbies quite easily (the latest being DYI perfume making).
