Dee is very nice and very communicative host. She lives in the house, the kitchen is common with her (and in some cases with other airbnb guests), but nothing else. Her home is very special, with a great neighborhood.
However, I can relate with one former opinion, which said that the many historical value made us very conscious of staying there, and because of the rules and notes about the things reminding you to be careful, it was not the most relaxing experience. (Don't think any serious thing: you can't open the window, can't roll your suitcase, etc.)
But this was only us, if you're into historical homes, and like to interact with your host, this will be a great place to stay in SF!
