I have been to San Diego several times before and this is by far the best place I have stayed. I traveled with my parents and sister and it was the perfect size for the four of us. Everything we needed was in the house - coffee, hair dryer, beach chairs, beach towels, etc. It is the ideal location - easy to find, safe area, walking distance to everywhere we wanted to go, and great parking. The beach house was newly remodeled and very nice - high ceilings, sky lights, comfortable bed/pull-out couch, clean, modern, well designed, great porch area, plenty of storage. I messaged Carlos a few times during our stay and he was quick to respond and always very helpful.
If you end up staying here, I highly recommend going to the luau at the Catamaran that is within walking distance. It is every Tues/Fri evening during the summer - great food and an amazing show. Also, World Famous is another great place to have dinner if you are looking for a place that overlooks the ocean, has great seafood, and is within walking distance.
