Good luck to your daughter and Ill say a prayer for her. I don't live in California but I am sure that possibly someone will come along and be able to help you. I know that when my sister was going through her cancer treatments that the hospital had something like a House that had bedrooms for families of hospitalized members that my brother in law stayed in across the street from the hospital. I would try calling UCLA and see if they have something like that available. I am pretty sure that they probably do.
Good Luck to you.
