Susan is one of the warmest and most welcoming people you will ever meet. She made me feel right at home. Susan picked me up at the airport and also dropped me off again, the rest you can do by bus or cab - really no need for a car, unless you want to explore more than just the city. Her flat is within 15 minutes of the Convention Center (by bus) and downtown San Diego. If I ever go back to the Convention Center, this is the place I'll stay.
