Me and my friend stayed in Jacqueline's place for 4 days. Here is what I can share with other guests:
Good things: Jaqueline respected our privacy; she allowed us to use many things in the house including her computer (because we didn't have a laptop and we needed a computer to plan the rest of our trip) and her tool box; she was very flexible with check-in; the house is on bus routes; there are different shops whithin walking distance; the neighborhood feels very safe.
Bad things: the public transportation system in San Diego is very bad, so it takes an hour or more to get to the attractions, but if you have a car, the house is pretty close to everything; the room we got was too small for two people and it was pretty stuffed (make sure you get the biggest room if there is two of you); very little room in the fridge; there is only one bathroom in the house.
