I was a single woman traveler, and there wasn't a single moment I didn't feel safe or my space respected while staying there. The host was home every time I was, but he was kind, respectful, and I never once felt uncomfortable.
The location is wonderful. It's in the heart of the Haight-Ashbury neighborhood, and it close to both a few Muni stops and a few bus stops. It's about a twenty minute walk to the entrance of Golden Gate Park, and I spent most mornings walking over and climbing to the top of Buena Vista Park eating my breakfast watching the Golden Gate Bridge emerge from the fog. I was in town for a conference downtown, and I took the Muni in everyday. Download the Clipper App, and it's insanely easy. About a 20 minute trip on the Muni to the Moscone Center. I will say, all of my coworkers stayed downtown, and they all wished they had stayed where I did after hearing about my experiences.
As a single woman traveler, I could not recommend this stay enough. Great location, great host, and the bed was incredibly comfortable. Even walking from transit stops late at night felt safe because of the neighborhood and how close the stops are to the home. Just a heads up though, it is on one of those steep hills San Francisco is famous for and you have to climb a decent chunk of steps to get into the home so if you have mobility restrictions, this home isn't for you. All of that being said, I highly recommend staying here.
