I really like Nancy's home. It's a guest house in the backyard of the main house and it feels very private. The kitchen had everything I needed to make a simple breakfast before heading out for the day. The bed felt so comfy that I slept very well.
The neighborhood is safe and Balboa Park is only one block away, I could easily walk to San Diego Zoo and spend a day there. Overall it was a great stay, highly recommend it to solo travelers or couples.
