Unfortunately, this was a very bad Airbnb experience and I stay in Airbnbs in the Bay Area regularly.
The unit is nicely designed and has modern furnishings, but the area (East Palo Alto) is sketchy and felt unsafe. I tend to arrive late at night, and I didn't feel comfortable arriving that late to this neighborhood. The first night was fine, but by the time I got back late night on the 2nd night, ants had infested the unit, including on the bed, the main floor, and the bathroom. I don't bring food into Airbnbs so these ants came from somewhere else in the unit. Once I saw the ants in the bed, I had to leave and grab an emergency hotel for the night.
To the host's credit, he responded promptly at midnight and refunded me the same night. He also said he would have pest control come by to check it out immediately. I felt he did the best job he could given the unfortunate circumstances.
