We had a wonderful stay for a week in July with 4 adults and three kids under three. The three bedrooms fit us all just perfect and there was a daybed with trundle in the living room if more people needed a bed.
We were so happy to be able to get the kids to the beach without leaving the house! The dock opens to a quiet little area on the Santa Rosa Sound. In the mornings the water is up to the rocks but in the evening/afternoon, there's a perfect little beach for the kids! If you want to go to the gulf side, it's only two blocks down the road and it was an easy walk with the kids. I recommend popping over there at night because it's just breathtaking!
The house is well stocked with what you need to make meals (even a little salt+pepper shaker set), wash clothes, and even includes hotel style toiletries! Each room has a tv with roku, though we only used the cable streaming on the living room tv. The dvd player might be broken, because we couldn't get it to work over the hdmi connection. There are bookshelves with dvds and books for adults and kids. There's a closet full of extra pillows and blankets in case you get cold (not a problem in July!)
It was very hot when we visited but the back porch has two big umbrellas that made it nice. We brought our own beach umbrellas and made a shady spot off the dock as well, which I highly recommend.
The check in and out process was seamless and we had no issues during our stay. We hope to come back next year in a cooler season!
