Nice, well-maintained, secure, clean home near SFO and the Bart. The host and guests were very nice, and I had no issue with noise. My room was upstairs, and I shared a bathroom with one other upstairs room.
The parking was a slight issue. There were a couple of times when I couldn't find a close place to park my car, but the host did her best to accommodate all of the guests.
The common area and kitchen were clean, well stocked with the basics, and offered coffee and tea, as well as space in the refrigerator for guests.
One suggestion I have is that closer attention be paid to the bathrooms. The shared hand towel didn't appear to have been changed more than once throughout the three weeks of my stay, and there were consistently rouge hairs in the shower.
I'd also like to mention that guests need to clean up after themselves when sharing a bathroom with others; it's just common courtesy.
That said, and overall, it's a big thumbs-up for me.
