We (myself, husband, our 16-year-old son, our brother and sister-in-law and their 3 and 6-year-old sons, and my husband's parents) stayed in July. Gorgeous, large home with big kitchen, two kayaks (we rented two more from Dockside Boat Rentals in Oxford, who delivered them), and lovely pool. Air conditioning worked great - even on the third floor. 7 minutes from town. Kitchen well-equipped.
Plenty of lawn for the kids to run around. We enjoyed fishing on the dock. We would absolutely stay here again. Did I mention that this place is gorgeous???
A couple nit-picks: the grill really should be replaced and located somewhere in the shade. Clear instructions for the pool cover would be a huge plus for both peace of mind with small children and for keeping the heat in at night. Also, the alarm went off unexpectedly and we had no idea how to turn it off. It eventually did so on its own. Stairs to the upper floors may be an issue with older people who struggle with mobility, but it wasn't a problem for us.
We really loved Combsberry; it is beautifully furnished and decorated to reflect its history, as it was built in 1730. Very peaceful location, perfect for exploring on kayaks. Jennifer was quick to respond with any questions. Great week and a lovely family vacation!
