Very good location next to Balboa Park. Also provided a lot of toiletries if you forget (toothbrush & toothpaste, shampoo, body wash, bottled water).
If you opt for paid parking garage, it could be a little confusing. There’s a beige key pad that you might have to get out of your car to input the code. Also some spots are behind other cars, so I would recommend asking for a spot that can’t be blocked in by others.
