I stayed in the Blue room for four months. I was a visiting researcher at Stanford University.
To me, the most important thing was the distance to the Stanford campus, which is within 30-40 min walking distance. There are also several close-by options to do groceries.
The room is clean and comfortable. It isn’t directly exposed to sunlight, and thus doesn’t get too warm even when it’s hot outside. The house is also nice and has a yard and a well-equipped kitchen.
Carina is a good host, always willing to help you out. She also organised some nice events at the house during my stay. For most of my time, there were three other guests in the house. The neighbourhood is very calm and quiet (as is all of Palo Alto).
Based on my undestanding, the blue room was decent value for money, given the rather limited options in Palo Alto and the overall high housing prices in the SF Bay Area.
