We very much enjoyed our stay at Rodanthe's place. It has some of the quirks you might expect in an older place-e.g., doors that lock only with keys, shutters that are held open by stones. The location is perfect and there is lots of space for a group (there were six of us). The porch has a beautiful view of the sea. The one shower is actually in a separate room from the toilet which makes it more efficient for getting a group ready to go.
There is no a/c. It was not hot in May with the windows open and after airing out the room, I was able to shut the windows and shutters. I am a very light sleeper and while the house is in a quiet location, there were dogs barking that kept me awake. It might have been too hot to do this mid summer so this would be a disadvantage if you are a light sleeper.
