My wife and I stayed at Chuck and Yvonne's place for 6 nights. They even accommodated a very late check in (12am) and the property was as described in the listing.
Being on a 2 month trip of the US we appreciated that the accommodation had appliances to cook and clean if we so desired. We also made good use of the old Weber BBQ whilst there which, as an Aussie, I enjoyed. Also, Chuck and Yvonne were always at hand to provide great local tips regarding how to get around, what to see and where to eat. There are also grocery stores and coffee shops within walking distance.
As you can see from the location it is outside of the main beach/bay areas of San Diego, however so long as you have a car or can afford the fairly cheap Uber fare then it's ok. Plus, most the main tourist attractions require travelling anyway so we didn't feel like we missed anything, except for noise and crowds.
The bed was comfortable. The wet room served its purpose but took a little getting used to - just a tip for future guests, anything on the ground in the wet room will get wet when showering so be sure to raise the floor mat and toilet paper off the ground ;).
All in all we would stay here again, especially given the reasonable price.
