This is a nice house with everything you need (even boardgames and info of San Diego). It's, as described, close to the downtown. We stayed for a convention and you could get to the convention center on a 20/25 minute walk. Take into consideration though that the house is on a hill like street, going down is ok but maybe you want to catch a taxi to go back up to the house.
We didn't meet Lucinda herself but we needed to call her during our stay and she was available and really useful.
