John & Christina's place was absolutely perfect. Not only was it a better deal than the majority of hotels in the area, the location, comfort, and convenience was impossible to beat! It was a quick and cheap uber ride from downtown (~10 mins, $7) and a short walk to Balboa Park. There are also countless restaurants within walking distance, a grocery store just down the street, and easy access to major roads if you want to go further. Finally, the air conditioner was so great to have as it only got down to the low 70's at night. I can not recommend their place enough as a perfect home base for your trip to San Diego.
