I've stayed at some very nice places through Airbnb: David's is the best. His hillside cabana has a picturesque view of San Francisco Bay, and huge windows to watch the sunset through. My drive to work was less than ten minutes, closer than whenever I stay in downtown Palo Alto, and much prettier, too.
David was a very gracious host and invited me to his house. I had a pleasure meeting him and his wife, and we had a great conversation into the evening. I certainly look forward to staying again at the cabana.
