Much-appreciated good basic no-frills lodging, and good people.
A few things to be aware of about this room:
It shares an acoustically thin wall with another room, so be alert for what your end of a phone conversation might sound like.
It might not be the best place to hole up in your room and study - the neighbors on the room's "window" side are outdoors or near a window a lot, so you'll likely be hearing them if the room window is open, and when it's not open, the air gets stale.
(I did not try the heatpump fan, does it bring in fresh air?)
Location fyi: I'd wanted to bicycle more, including up (west) to El Camino Real, but the route didn't feel inviting, so during my visit I ended up driving more than expected. The house's off-street automobile parking is along a single-car-width driveway, but to my surprise this worked out just fine, fellow guests were excellent about cooperating to move cars as needed.
(Bring your mask if you're bicycling in Palo Alto, as construction work along city streets does seem to raise considerable dust.)
This is a great place to stay especially for someone whose visit is oriented east toward the bay and companies there.
(One or two other things I have mentioned to the hosts.)
