I really need help!!

Hi everyone!!

I really need your help!

Here is the point: I'm arriving in London next Saturday and I have nowhere to live. I had my couzin living in Shadwell, but she gives up on me at the very last time (to be more precise... Yesterday...)!

So I am really in trouble.

I'll be in internship in Lewisham but I don't want to live there as people largely advise me to not stay in this place.

So I am looking for a flat share or a house share, near Lewisham, in a not dangerous place!
Do you have some advises for me, do you know websites or anything which could help me to find a place? or if one of you is looking for a room mate... LOL
I am French, and at present I am still in France so, I 'll be able to visit only since saturday in the afternoon, as it is really late and i can't come in london this week.

Thank you in advance for your help!
I hope I'll find something before I leave..

Best regards,
Tititia
