David is a great host! He is a very nice person who is very welcoming and made me feel comfortable staying with him. David provides great recommendations (such as activities and foods to try), is very easy to communicate with, provides the essentials needed (such as towels and toothpaste) that you might have forgotten, and the Airbnb was nice and tidy. I would definitely recommend to stay with him and would not mind staying with him again if I visited SF in the future.
