Dominicans in San Ramon, California

Hi. I need help. My daughter is relocating to California this month. The company is located in San Ramon. She is planning to stay a few days in a hotel. We need to know closest airport, how to look for apartments. If San Ramon's rent is too high, any town close by safe enough and if possible any real estate. Any hotel not 5 stars but safe.
We are lost we do not know how to start. Never been in California. I told her not to rent until she gets there and see where she is going to live because she will be stock with a year lease.

Any help will be appreciated. Any Dominicans there?

Thank you. No sponsor. They give her relocation fee or hotel fee and then she has to rent. She is trying to get the relocation fee. Thank you for the information.
