German student staying for a 1-month internship

I am a 22-years-old german student and currently looking for a place to stay from 24 March to 19 April as I will do a 1-month internship in London. I am originally from Berlin but I have been studying law in a smaller city called Freiburg for some years now.
I am really into sports, especially I like running, dancing and tennis. I would describe myself as a positive and open-minded person. I am easy going, can adapt to the needs of my flatmates and always clean up after myself, as I am living in shared flats for years now.
In terms of my lifestyle I am eco friendly and prefer vegetarian food.
I would appreciate to hang out with my flatmates and enjoy a warm and friendly atmosphere at home but of course think that at the same time everyone needs his own space.
I already had some longer stays in other countries but am really looking forward to this new experience in London. Do not hesitate if you have any questions.
