I have a home in San Diego & needed a place to go while the wood floors in my home were being refinished.
Kate's place was awesome----close to the 805 (which is the backbone of San Diego). So yes, you do need a car.
The home is spacious & clean & I was welcome to relax anywhere I wanted. Although there were several folks that lived there & some guests, it was surprisingly quiet, & everyone was respectful after 9:00 p.m.
Kate was also available, but didn't hover, making you feel very welcome.
I highly recommend staying here if you are in San Diego.
