Pros: Close to the airport. Spacious! Several comfortable beds and bedrooms. Beautiful view from upstairs windows of sunrise.
Okays: Could hear white noise from the nearby expressway from the livingroom and front bedroom - but honestly less than we expected once we realized how close it was to the highway. And the plus was that it was easy to get to from the highway.
Cons: Cleanliness was a bit lacking (found a hair on bedding, spiderwebs in windows); overall okay, but if you were fastidious, that would probably bug you. Only one small love seat in the living space that was slip covered - it seemed like it was likely an interim measure - but not what was advertised and definitely not enough seating for our family.
Overall we enjoyed our stay and the drawbacks weren't enough to interrupt our stay or take away from our enjoyment of our stay just outside San Fran :)
