I fully appreciate this post is not in the correct forum, but thought I’d risk it.

Does anyone know of any good, centrally located and easily accessable hostels/motels in Los Angeles, San Francisco, San Diego, Phoenix and Las Vegas?

Preferably, but not essential, would be a hostel/motel at, or close to, the airports of the respective cities, or easily accessable by public transportation.

Please help if you can.
