My nieces and I stayed at Susanna's beautiful place during Comic-con 2015. It is a beautiful little cottage style place with a living room, bedroom, and bathroom. It was perfect for the 3 of us. Yup. The 3 of us. One of my niece is a small child, so I guess 2.5? But Susanna was kind enough to accommodate all of us and gave us a great cafe recommendation called Cardamom. Delicious. She also provided fruit, sparkling water, and coffee. It only took about 10 minutes at most to the San Diego Convention Center. Street parking was abundant in front of her place. Quiet, safe, beautiful neighborhood close to practically everything. I definitely plan on requesting to stay here again in the future.
*heads up though, bathroom is a little small so larger adults beware. There is a drawer right in front of the toilet so sitting and getting up might be a little difficult.
