My family, in-laws and our dog stayed at Mary's house for almost a week for a staycation. As locals and former residents of Mountain View, we really appreciated the excellent location of Mary's house. It's within a 15 min walk to downtown and super convenient to restaurants and shops. My father-in-law loved that it was short drive to Stanford so he could visit his old campus.
The house has everything you need for a stay of any length. It's also really well set up for multiple families traveling together to have their own private space. The master bedroom and 2 other bedrooms are separate from each other and the common areas so you can sleep in/get up early without disturbing others.
The backyard is awesome. Shaded, large, and kid + pet friendly. The kids can play on the playground set, adults can have a drink at the outdoor dining area, and you can play fetch with the dog at the same time without running into each other.
Mary is also super organized and communicative. Great host and great house :)
