Staying in George's house is one of my greatest experience during my stay in the States. George saved his front room for me as there is a construction site outside the room that has been previously advertised. He is so considerate and nice and helpful. And his cat Kuma is the sweetest cat I've ever seen. Parting from them on the leaving day made me feel sad and sentimental. I really recommend staying at his place, especially you are a cat person:) Castro is one of the best communities in San Francisco as far as I see. It's beautiful, peaceful and safe. And you can get a spectacular view from George's balcony.
