Carl is welcoming, very friendly, interested in people, respectful of our privacy. It felt like home with family or friends. Carl and Michael are quick to answer our questions. Well Organised. Gives a lot of information about what to do in San Francisco as much in terms of restaurants, activities or transportation. The indoor parking place is a plus in San Francisco. We feels a lot of love and life in Carl home. Great location. We fell in love with Rosemary (the cat) just as warm as her master. A big thank you Carl for sharing your house with us. If we go back to San Francisco, we will go back to your home.
