Check out this site. I too was looking for a rental home, as this is my second trip to AC. http://cayemanagement.com/
Stayed at the Palm House last time I was there. Absolutely great, no complaints at all. Pool was nice. I fully intended this time to stay at a rental home, although the Palm House was twice as large as I needed this time, 3 bedrooms. My friend and I found that Coconuts has a Penthouse suite with 2 bedrooms and kitchen area that is more than 1/2 price of many of the rental homes. I am leaving this Saturday for my stay, and will let you know how the accomodations are. If you are dead set on a house, check out the above link if you haven't already. They have atleast 22 places they manage on AC.
