Looking for Flat to Rent in London

Hi everybody!

Few friends are coming to London for a one month stay. They are looking for an apartment to rent. They've tried an agency, which came up with a place in Canary Wharf, which goes for 1,000 pounds/wk.
If any of you knows of a place in a good area (safe, easy tube access), at a reasonable price, please let me know. I believe they are looking for a 2 bedroom apartment.
Truly appreciate your help!
