The Place Itself:
This unit is cozy, clean, and has lots of character! The front yard is nice to relax in and has a play area suitable for young children (ages 2-5). From the yard you can see the owner's chickens (which my daughter loved). These chickens are clean, quiet, and friendly. The unit is on the smaller side, but has all the necessary amenities (coffee maker, laundry, filtered water, pots/pans, bathroom toiletries, etc) and also has a small closet of toys!
Two minor drawbacks:
1) No direct access to the bathroom from the living room, you must go through one of the two bedrooms. This means using the bathroom is a bit tricky if the two rooms are occupied (by children sleeping, for example).
2) No TV in the living room. The only tv is in one of the bedrooms. This means if your kid is asleep for the night in that bedroom, you're not watching any TV.

The Location:
5 min drive to Zoo/Balboa park
15-20 min drive to assorted beaches
5 min drive to various foodie places (good pizza, tacos, pubs in North Park)
One minor drawback:
Parking is a huge pain in the rear. There is only street parking available, and this neighborhood is busy! Several times, I had to circle the neighborhood for 5-10 minutes and ended up parking 2-3 blocks away. That's a bit annoying if you have young children and lots of luggage to load/unload.
The Hosts:
Polite, nice, friendly. Norman's wife came by when we first checked in to make sure everything was ok and was always checking on us (in a good way) in the morning as there is a shared fence between the property and the owner's property.
Overall, I would recommend this place to younger, smaller families looking to primarily enjoy the zoo/balboa park in San Diego for 2-4 days.
