This a wonderful, clean and totally private (because you have the unit to yourself) place. I loved the many healthy plants, and the little thoughtful touches throughout, for example: the dots and labels on the light switches to help you know which switch toggles which light in which positions, provided toothpaste, power boards on both sides of the bed, USB charger, board games, ...
When you arrive, make sure you enter through the sliding glass door rather than the other door opposite like I tried because I hadn't read the description properly; Elena covered for my poor reading skills and pointed me in the right direction within seconds of me messaging her (she was away on a trip to Chicago).
Elena and Alberto live in a separate house on the property. They're among the most kind-hearted, thoughtful people you will ever meet.
The place is conveniently located to busses to various tech companies in the area (this is how I got to work during my visit); the Caltrain station is only 10min walk away.
