Fits the description, you have your own space to sleep in the garden and share the kitchen and bathroom. Humble but convenient home. Rosario and Thomas are both genuinely great persons, offering to cook for us and share their meals almost every night of our 4-night-stay. Like said in description, there are dogs, a bit invasive but nice and really not a problem. Great discussions, they were ready to help us anytime, and they gave us rides to the bart (which is a bit far away but uber is THE solution in SF) or to different activities.
Would recommand for an affordable place to stay and for meeting with the owners.
