San Diego specifically LaJolla and Pacific Beach is highly recommended. The accommodation can be reached by bike in about 10 minutes and on foot in about 30 minutes. In our experience you should definitely go by bike. I would leave the car at home (not worth it)
Anthony and Martha were very friendly and extremely helpful. This simplified our stay and made us feel welcome and in good hands.
But what disturbed us was the cleanliness. Unfortunately not to our complete satisfaction. The floor was very dirty and not cleaned at all. There were hair everywhere on the floor (also stuck the hair on doors and walls), dusty, dirty and partly sandy. We had to walk around the apartment with socks that were completely black afterwards. Unfortunately, a big minus point. Since the apartment is probably already relatively old, a retreading would certainly be good. In certain corners (bathroom) it does not look so appetizing anymore.
