We really enjoyed our large family gathering of 10, including 4 children. They liked playing outside, and appreciated the beach toys and games.
We also enjoyed eating outside, and watching the fireworks from the upstairs deck. And going to the beaches! Mission Bay has a fun playground, not walking distance but not far to drive. Unfortunately we were there during an unusually hot humid spell, and parts of the house are hot if avoiding AC.
Overall we enjoyed it a lot, and Aaron our host was responsive to any questions or problems.
