My family (me, my wife, my two kids ((ages 12 + 15)), and my wife's brother and his family )(wife and 3 kids ages 3, 5, 7,) spent five nights at the house. There was plenty of room and then some for all!
The beach is right across the street, and very easy to access. The younger kids really enjoyed playing on the beach and exploring in the water for hermit crabs and starfish and other sea creatures. The beach is very nice, and not too busy. It's not like the waters of the open Gulf or the Atlantic, but nice.
The house is not only very spacious, but was clean and has everything you need.
The back dock on the channel is an added bonus for putting in kayaks, or doing a little fishing. We kayaked both in the bay and in the channels, and caught a few fish. We even saw a few manatees in the channels.
The hosts were very helpful and were quick to answer all the questions we had before, during, and after the stay.
Highly recommend staying here. Especially families with kids.
