We stayed here in November, and was very satisfied.

One block south of Duvall, half a block from Hemingway's place. Price was $119 for queen bed room, but when I hesitated, they immediately offered an upgrade to a King bed room at same price. Includes breakfast on pool cabana, and includes earplugs. You can easily walk to all the waterfront areas from here. Be aware that there is limited off-street parking, so, if you can get a space, plan on parking it and leaving it!
Enjoy!
