Yuca was a fantastic host! He was very communicative, helpful and welcoming. His place is beautiful and in a great location-- just a <10m (downhill) walk into the Castro. We loved the neighborhood with beautiful houses and great views of the city.
The bed was very comfortable and the space was so quiet. The room is the lower level of his home with its own private entrance, so we never felt awkward or intrusive. It's also generously sized for sharing with your travel partner.
I'd definitely recommend Yuca's place and would certainly stay again if I'm back in SF!
