We went to San Francisco for a business conference, and I would definitely recommend staying at Guillermo's apartment. When we visit the conference next year, we would love to stay in Guillermo's apartment again.

We've stayed here 4 nights and the apartment is really great. It is spacious, clean and modern. Furthermore Guillermo had some basic shopping done, so you don't have to go to the supermarket for some coffee. That's very pleasant after a long journey. The neighborhood is ok, it feels safe and there were some shops around the corner (walking distance).

Communication with Guillermo is easy via the Airbnb chat. He also did send us some ideas for sightseeing.
