I have not had the chance to meet Laura, but Larry is a very nice host, available and thoughtful. The house is pretty big with many good things I loved like the view from the terrace or the patio ! The location is really good : it's easy to go quickly almost everywhere in the city. The room is quite clean, functional and not expansive for SF. If you don't mind the little natural light in it, you should definitively book Larry's room !
