Carl was a great host; responsive, thorough and accommodating. He's present every morning in the house to chat or to provide any help/information as needed. He was engaging and warm. There were other guests staying, but no problem since everyone was considerate to each other. Rosemary the cat was a nice addition and always ready for a cuddle, in fact she demanded them! The room was exactly as it looked in the pictures n description provided. Location was good, within walking distance to most other SF districts (but bear in mind this is SF, so some of those distance will require hiking/climbing/scrambling). Summarizing, Carl's place is THE place to stay in SF, heartily recommended!
