A professional looking for a doublebedroom in June

Hi,

I am Marta, a cabin crew member, looking for a double room in a professional, house or flat ( no couples, no landlords ).
I am not at home as much as other people. I would like to find a place where I can feel at home. I am sociable but I like to have time on my own as well. I would like to live in a safe area with connection to public transport. I would like also to share with three people maximum, including myself.
I am moving from my actual place at the end of June, beginning of July.
