This place definitely has a charm. The house is situated on a very steep hill and about 15 min walk to the Bart station (in total, it takes about 35-40 mins to get to San Francisco). The bedroom is large, and the public spaces are nicely decorated. I was traveling for work, so I was mostly there to sleep. The bed was extremely comfortable and it was nice that I had the option to lock the bedroom door with a key if I chose (though I didn't feel the need to do so). Cathy was communicative and helpful when booking the reservation. When I showed up, she had someone stop by to make sure I was situated. She does not live on the property, so it's unclear who shares the space. I saw her son walk past once, but for the most part it was a very quiet space and I didn't really run into the other occupants while I was there. I had no issues gaining access to the bathroom in the mornings. Aside from a couple minor things that need to be adjusted in the bathroom, the place was perfect.
If you're looking for a lot of host interaction, this is not the place. But if you want a very quiet shared space close enough to public transit, it's great.
