Very responsive host! The building is a hostal and the room is generally clean and located close to several popular areas in downtown San Diego. Overall I recommend staying given the price and location. You can also find street parking nearby or private parking (I didn’t have to use it in November).
Be mindful that you’ll find homeless people nearby. Sadly this is a problem affecting big cities in the West Coast, but note that most likely they will be minding their own business, so it should be safe.
