We really enjoyed staying near Balboa Park - a quiet cul de sac near the park. The unit is quiet bright, despite it being a basement apartment; it's large and sparkling clean with a very comfortable bed. We really appreciated the double sink in the bathroom, large shower and full size washer and dryer.
Be aware that this unit is in a basement of a home with a toddler, and you can hear pretty much everything through the ceiling (e.g. footsteps, voices, conversations, crying, playing), so even though it's a separate/private unit, the sound isn't insulated.
