If you are looking for a place to be close to all of the wonderful tourist opportunities that can be found in San Diego, while also keeping a bit of distance from the higher density areas, I highly suggest you consider booking this spot. I stayed here for just under a month, while receiving professional training nearby.
The unit is beautifully furnished with a massive, amazingly comfortable bed. The kitchen has ample space for cooking meals on nights that you would prefer to stay in and I was left wanting for nothing during the duration of my stay. I had no need to rent a car (although I did twice for weekend excrusions out to the desert, which I highly recommend). Uber rides are typically very reasonable and usually land somewhere in the $8 to $12 range for most drop offs in town.
If you're looking to walk, you're set as well, they're in a central location up on a hill, so you can walk downhill to wherever you're headed and then Uber back, if you don't fancy an uphill walk; there's also plenty of Lime scooters kicking around that can help lug ya back up too.
Overall Libby and Jeremy run a wonderful rental and will go out of their way to make sure that your stay is as amazing as possible.
10/10, would (and probably will) book again!
