Jon is a very communicative host and answers promptly. Jon's place was convenient since it's a close walk to the BART. This is a great place if you plan on exploring the city the entire time you're there. You can definitely hear the upstairs; however, the family provides earplugs if you're a light sleeper. The bed is not the most comfortable since there's a crack in the middle from the two mattresses that were put together, but when you're tired from exploring you're not too picky. The breakfast is more of an on-the-go snack in the form of granola bars. As for the bathroom, it could use better ventilation so the towels can dry - we remedied that by leaving the fan on the entire stay.
