Dear Stephanie:
I know you are looking for someone to rent a room, so it's a pleasure to me give you all the information you need.
My friend is called Susan. She's 23 and lives in a very good  neighborhood near to the university you will go in California. Her family i'ts very cool and friendly, you won't have problems with them. Susan goes to the same university as you and she studies biology, she would give you a tour of the university if you want, it's a very good option for you!
About her personality, she will be always there for you because she is a very good woman. You can resolve all the doubts you have about your studies with her. Also, she likes to sign, to cook and do some sports like tennis, basketball and soccer. But the most important thing, she loves the beach just like you! So you would go to the beach always!
I hope this information were good for you.
Love
Javiera
