We had quite a nice stay here (2 adults for 2 nights)! The room was very clean but not large (but if you’re traveling to San Diego, you probably won’t spend enough time in the actual Airbnb to care about spaciousness).
The wifi was not good (couldn’t complete a basic speedtest!), the bed was a basic IKEA setup, and the large front windows only had thin, mostly see-through curtains (we used our bath towels to add a bit of privacy).
But if you’ve got a car and don’t plan on cooking, this is a really solid base of operations for a couple days in San Diego!
