The unit is very nicely decorated and comfortable. It sits in a cluster of five duplexes just steps from the beach. This one is the farthest from the beach, and you can only actually see the beach if you sit out on the small front porch. I'm 6'4", and the cottage felt cramped, but others may feel differently. It says it sleeps up to 5, but really one small child plus 2 adults would be all that would fit comfortably.
It seems like the Sanibel beaches are covered mostly with larger condo complexes, and small, more intimate cottages like this one are rare. If that's what you're looking for, this is a good choice.
