Billy & John's house is the most artistic place I've ever stayed! It really feels like living in a mini museum& art gallery! And very comfortable and well arranged! They know everything about San Francisco and art, culture, history, photography, movie and etc....anyway...stay with them for a couple of days really saves your education expenses on fine arts!! What's worthy mentioning...they are both very cute and handsome and incredibly sweet and nice to visitors!!! I assure you stay in their house would make anyone's trip in SF unique and unforgettable!!!
