Robert and Shelly are actually managers of a rental company called Serenity Executive Rentals. After the initial booking, I did not communicate with Robert and Shelley anymore, and instead was contacted via email by their employees of the management company.
The house itself was nice and as pictured in the post. It is in an apartment complex and is the bottom floor of a 2 story apartment block. One thing to note is that the third bedroom has sliding doors and hangs immediately off the living room.
Parking is tight, but there is a garage allocated to the apartment that had space for one car. The location of the house is a 10 minute drive to the heart of Silicon Valley which makes it a good homebase for work related travel. The internet in the apartment was reliable and fast. It was a satisfactory home base for my work related travel.
