Looking for accomodation in London

I'm Stella, i'm an 18 year old from Australia looking for a place to live until late December, I know I'm a bit young but ive been working for 2 years to move to London and am a fully capable, mature person. i'm looking to start renting from April 27th, I'm reliable and clean and just looking for an enjoyable gap year before university back home!

I'm looking for a friendly share house in London preferably not too far from the city centre as that's where I'll be working. im happy with a single room as long as there is a communal space (lounge room/kitchen) I can use and a bathroom!
