I have stayed at the Edgewater off and on for over twenty years. It is one of my favorite locations on the cape. It sits right on one of the nicest beaches on the Cape, and believe me, i have swam them all. The beach is a sound/ocean beach. The water is usually warm and gentle. A one foot wave is a big wave at this beach. Often during low tide you can walk out forever at this gorgeous beach. It is safe enough for children and yet not so tame that adults cant enjoy it.
Edgewater used to be a motel, but it is mostly a time share now. However I believe you can still book rooms on occasions. There is a great indoor outdoor pool surrounded by glass. You can swim from the greenhouse section, out of a small opening into the outdoor pool. The grounds are beautiful as well, and its a short walk to their exceptional beach. In addition to suites, there are small townhouses available across the road. These are near the great restaurant the "Ebb Tide"
