Have you considered university residences? These say they are available from early June. http://www.wmin.ac.uk/comserv/halls.htm Standard rates are about 25 pounds (less for young travellers) at Westminster College. You can book online. The website says: Ideal for self-catering, each Hall has well equipped kitchens,

supplied with crockery and cutlery, and access to TV lounges,

launderettes and public telephones, adding convenience to great

savings.

Here are other lists: http://tinyurl.com/yrruf This lists many.

Each has different facilities and prices and dates available.

I have stayed at one university residence in Canada (Waterloo) and have stayed in youth hostels in Switzerland and Germany (with my teenaged children).

If you can cook some of your meals (or at least have picnics, find reasonably priced accommodation, you should have a great time in London. Museums are free; it's a great city to visit. Just pricey for accommodation ;-(
