Rene and charles were grest. They were very hospitable. When we arrived fresh baked cooked were available. They gave us some advices for visiting the city. The location couldn't be better. The BART (local subway) was within 5 minutes walking distance and less then 10 minutes with the BART were at union square. In addition, their bathroom was amazing. If we are going back to SF, we certainly would stay again with Rene and Charles.
