Double room with en suite

I am a British/Italian professional, 52 years old. Within the household, I am independent but approachable and open to socializing with my flatmates. I will always make an effort to promote a happy and drama-free atmosphere in the household. I am a polite, clean and friendly flatmate (have been sharing in London for many years, always positive experiences). In my spare time, I like travelling, reading, watching films and series, cooking, video games.

I am looking for an en suite double room (or a double room with private use of a bathroom), ideally in a modern flat with large rooms and a large shared living room.
At the moment, I am only interested in short lets (1/2 months would be ideal, 3 months top)
