I could not have had a more perfect host during my time in Mountain View! I was there for work, away from my family, and I loved how Dianne was both great company and very conscientious about giving space. The room itself was great: the bed was surprisingly comfortable, there's some shelves to put your clothes during your stay, and the shared bathroom was close to my room but far enough from the other rooms, so it felt very private. Dianne happened to make zucchini bread the night I arrived, so I had some for breakfast, along with tea and plums from her garden. The medium-sized dog and tiny cat were very cute and friendly.
The location is great - within walking distance to Castro St and CalTrain. And I felt quite safe walking around late at night.
