Working in London for 2 months looking for a room

My name is Keira, i’m 19 from Australia and i’m looking for a place to stay for 2 months while i work in London and I decide whether I want to stay long term before I travel Europe after summer. i’m super easy to get along with and love to go out but also have quiet nights and read. I have family in the south of england and cousins who perform in the west end but i have a job lined up in the city so im keen to find a place to stay! I arrive early July
