We absolutely loved our stay here! The photos undersell this place - it's a classy casita attached to their house, but with lots of privacy. You'll enter through your own side gate and have your own enclosed patio.
We had everything we need for a comfortable stay for the week. The bed was super comfy. We loved the little detailed touches - a Bluetooth speaker, bathroom necessities, gold silverware, pretty art, plenty of hangers in the closet, etc.
The place does face the main street, but it's overall very quiet thanks to the privacy fence. If you hear random "thumping" at night, we figured out by the third night that it's the waves hitting the seawalls a few blocks away. The casita is within a ~10 minute walk to the beach and close proximity to everything in La Jolla.
We interacted with David and Juliet (as well as their pups) a few times and they were both very friendly and hospitable! We would absolutely stay here again!
