my husband and I had one unit and our daughter, her husband and 3 sons (7,4,2) had an adjacent unit. We were within walking distance to the pier and beach.
Although the units were on the small side, they were clean and well appointed. The hosts were very accommodating, responding quickly to any questions we had. Our major concern/complaint were the mattresses but we've had bad mattresses in other settings too.
Our grandchildren really liked the option of just dropping into our unit.
