Coworker and I spent 2 nights here on a biz trip, and the profile pictures really don't show how amazing this place really is - if it's open during your trip dates, book it. Seriously, do it now before someone else does.
Hosts were great - super welcoming, made us feel right at home. Took the time to walk through the house w/ us to show off where stuff was, where we were in the city, how we could get around, what was walkable, how to get transportation, etc. Would have spent more time with them (especially the musical jam sessions on the patio out back!) but was in town for work and just didn't have the bandwidth.
Garden is just incredible and would be a great place to sit outside to work (or just get centered again) when it's not raining. It's like 3 stories of stairs, water features, seating areas, and great views of the city & neighborhoods. Solid wifi everywhere w/ additional access points out in the garden.
You do share a common bathroom with another room, but it's clearly explained out before you book. You have free access to other bathrooms in the house, but we didn't find it a problem to even need it.
Will definitely check here first for future trips back to SF.
