We stayed 10 nights and overall had a very good experience. The Airbnb was sparkling clean and had fast internet that supported both of us working from home, extra nice appliances and fixtures (like the shower head was powerful, the sink was fancy), and many thoughtful touches (e.g., hand soap, a fresh dish sponge, plenty of dishwasher and laundry detergent pods, beach toys, and even snacks). The proximity to the beach is awesome and makes it easy to go for a jog or bike ride nearby. And the hosts are super responsive and helpful. They even let us visit the Airbnb before booking to check it out! It felt like an Airbnb Plus.
The only downside for us was that unfortunately there were mice in the kitchen during our stay. Apparently this isn’t totally uncommon in San Diego homes near the beach at certain times of year, and it doesn’t necessarily seem to correlate to cleanliness of the home. The hosts were very helpful in handling the situation.
