In short: We were pleased with our stay and WOULD DEFINITELY stay here again.
This property worked VERY well for our VERY extended family! The house is 4 bedrooms which worked for my wife and me as hosts, our single son, our married daughter & her husband, and my aging father and stepmom. The two cottages were perfect for our daughter's family (mom/dad/4 kids 1-8 years old) and our son's family (dad/mom/one 10-month old)!
The house stays as cool as you want - a big plus for the warm, humid weather we had. The kitchen was well equipped including a slow cooker and a pitcher for brewed tea or mixed lemonade, plus plenty of pots and pans to cook whatever you want. The private pool was nice (the water was clean, clear, and refreshing), and the private "cabana" screen room and pier were fun as well.
The main house is older, so be prepared for a few things that are less than brand new: somewhat "rickety" kitchen cabinets, a "sticky" front door, and a few other odds & ends like that. NONE of these was significant or detracted from our overall stay and enjoyment.
Google maps will try to take you in on "Shady Lane" which doesn't work. Apple maps has it right: turn north into the RV park just west of the house, and follow the small sign to turn right and access the driveway.
If the configuration of the property (house & cottages) looks workable for your group, book it! You won't be disappointed.
