Inna and her husband are so welcoming! She contacted me several days ago before we arrived in SF to give me any possible help. They provided all the things mentioned on the list. More touchingly, self-made cookies, teabags, and red wine were already awaiting when we arrive in a very late night. They even prepared a Chinese version of travel guide, which is very accurate and informative. We owned a separate bedroom and toilet, where we enjoyed quite staying. And they shared kitchen and bathroom.
They are always ready to help us or answer our questions. I love them!
The neighbourhood was quiet, beautiful, and safe. It's located close to an university and a large lake. Supermarkets and food stores are 1 minutes walking away from her house.
