JoAnn was a wonderful hostess with a beautiful home. I was able to walk to the library and downtown as well as take the ferry to Coronado. She's also very close to Balboa Park if you're interested in exploring there. JoAnn was very knowledgeable about up and coming areas in the city and is great in helping plan activities during your visit. If you're interested in yoga, she also doubles as an instructor and holds classes in her home.
I would absolutely visit JoAnn again and recommend it to anyone visiting San Diego.
