Is there any double room out there?

Hi! I am a professional italian female in her 30s looking for a double room in Hampstead, Highbury, Finsbury Park, Stoke Newington, Walthamstow.
I am very easygoing, clean and open-minded person.
I've lived for years in shared house and I've always had good relationships with my flatmates. I love cooking and share dinners with friends.
I love outdoors activities, trekking, diving and yoga. I'm a musician in the spare time.
It would be nice to have a common space and a small garden (I love gardening). I'm available to move after the 10th of January 2018 and I have a budget of ?750 pcm, however I can stretch a bit more for the right property. I don't mind to share with males or females and I don't care about the age.
