For a home base that's roomy enough for a family and that comes with cooking facilities, consider renting furnished "flats" (what apartments are called in Britain). These can save you money, especially if you're traveling with a group. If you're interested in home-exchange, but don't feel like sharing, some home exchange directories list rentals as well. If you want to deal directly with local agents, get a personal recommendation from someone who has used the company; there's no accredited rating system for apartment rental standards like the one for hotels. In addition to the options listed here, the London Tourist Board has accommodation lists.

No matter what your age, you can save on lodging costs by staying at hostels. In some 4,500 locations in more than 70 countries around the world, Hostelling International (HI), the umbrella group for a number of national youth-hostel associations, offers single-sex, dorm-style beds and, at many hostels, rooms for couples and family accommodations. Membership in any HI national hostel association, open to travelers of all ages, allows you to stay in HI-affiliated hostels at member rates; one-year membership is about $28 for adults (C$35 for a two-year minimum membership in Canada, £14 in the United Kingdom, A$52 in Australia, and NZ$40 in New Zealand); hostels charge about $10-$30 per night. Members have priority if the hostel is full; they're also eligible for discounts around the world, even on rail and bus travel in some countries. Members of the Boy Scouts may want to consider London's useful Baden-Powell House, which offers rooms for as little as $25 a night for Scouts and their families. Non scouts must pay a bit more.
