Cheapish London Hotels

[blossomsmine]

Anyone got any tips on booking a weeks stay in London, Marylebone area for three people?? We will be staying for a week and need to do this as cheaply as possible. I have looked at Holiday Inn but i don't really have any idea of what is a good price etc., There will be two adults and one child.
Thanks!

Travelodge -there is one in Covent Garden and a couple on Euston Rd but don't know about anywhere else offhand.
Otherwise try Superbreaks website - deals on hotels that are often cheaper than booking direct.

YHA or Easyhotel.

Thanks. Not heard of Easyhotel, so will give all the suggestions a go.
