Alex could not be a better host. The day I arrived he explained everything about the house, showed me a guide (made by himself) for places to eat and drink and other relevant info about Palo Alto.
The bed and the bath are excellent, I had very good nights of sleep there (I stayed for 16 days). The street is very calm, lots of space to park. I can not imagine a better place to stay if you need a calm environment, with all facilities, very close to Stanford.
