It's a decent place to stay, but few things that surprised us when we stayed: there's no oven, the house is located on the edge of a hill with a really steep carport, you can hear a lot of external noises and Roberto lives on the property.
This location did provide access to all the different sights we wanted to see in San Diego, like the zoo, the aquariums, downtown San Diego, the drive-in theatre, and more. The house was really clean (you could smell the cleaning products when you walked in). The beds were comfortable and the stove and microwave worked allowing us to cook some meals during our stay.
