I stayed here for about a week. If there is not hot water on your first day, make sure you message Patricia, because there is definitely hot water, they just might need to turn it on.
The listing notes that there is no AC, but just keep that in mind. During the day, it gets pretty warm in the RV, but it feels fine during the night. There is a fan in the RV, but it doesn't work very well. I ended up having to buy one because it was so hot during the day.
The driveway is definitely a little tricky. I drive an SUV; I would turn around at the very top of the street so that I could more easily get into the actual driveway. Then, when I was leaving, I would back out towards the house so that I could drive forward down the driveway rather than backing out.
It is nearly impossible to sleep in on the weekend as there is construction that starts fairly early. It wasn't an issue for me because I worked very early in the morning, but just keep that in mind if you want to sleep in on the weekend.
Overall, I actually did enjoy staying here. The location was great; it took about 15-20 minutes to get most anywhere in San Diego. Patricia is really good about responding quickly if you have any questions.
