We enjoyed our stay here. The home is in a great location, is immaculately clean, and has lots of technogadgetry that keeps everything secure and easy-to-use (electronic locks on all bedroom and bathroom doors, motion sensors on most of the lights, etc.). The hosts were exceptionally responsive and helpful.
I want to comment a bit on the shared nature of this space, since that was our biggest hesitation about booking. I normally like to book an "entire place" because we like to have private space to cook, eat and hang out outside the bedrooms. In this home, the bedrooms and bathrooms are private and secure but the kitchen, dining area and living room are shared by guests, the owner and a tenant. We never actually saw the owner during our stay, and while we did see the tenant occasionally he was very respectful and spent most of the time in his suite. For the most part we were able to use and enjoy the common space as if it was our own.
That said, it does not feel quite as homey or "lived in" as some of the airbnb's I have stayed at. The kitchen is reasonably well stocked and has all the standard appliances, and the living room has a couch, love seat and a coffee table, but that's about it. It feels a little spartan. There's no TV, and only 4 chairs at the dining table. If you're looking for a place to spend a lot of time hanging out at the airbnb with family or friends cooking, playing games, watching movies, etc., this may not be the best option for you. But if you're looking for a clean, comfortable place to sleep and whip up a few meals between seeing the sites of San Francisco, this is a great home base.
