We were a family of 12 (8 adults and 4 kids). We ended up putting all the kids together in the large master bedroom so that the adult couples could all have their own private rooms.

The location was fantastic:
5 minutes: to the San Diego Zoo
Under 30 minutes to: the San Diego Safari Park, Aquatica, Cabrillo Lighthouse, Mission Bay, USS Midway.
There's a supermarket a 2 minute walk away which was very convenient for picking up anything. And with 2 kitchens available, we had plenty of room for cooking. There are also tons of restaurants nearby for when you don't feel like cooking.

The kids (really all of us) had a lot of fun in the pool. We used it almost every day of our stay!

The hosts we're very accommodating and allowed us to show up a few hours early. They were also very quick to respond when we needed things or had any issues.
