Joseph's home is a real treasure: old school airBnb in that it is his home and not some impersonal rental. His description is very accurate. We enjoyed our week surrounded by his books, artwork, furniture (comfy bed), thick towels, and well-stocked kitchen. Loved his private oasis of a patio where we had morning coffee or an evening cocktail. (There are also nice lights that provide extra ambiance after sunset.) The views of the city skyline and of the bay at all times of the day were a bonus.
We never had trouble finding a parking space, and didn't mind the stairs from the street at all. Joseph was a great host: good instructions, very responsive, checked in to make sure everything was OK, and offered many nice touches like the refreshments in the fridge and the coffee. We loved having a home base right in Mission Hills. We really hope the next time we visit San Diego that Joseph's home is available!
