The cottage is indeed in it's own grounds (which are very nice indeed) - and we had exclusive access to the pool throughout. The cottage is well equipped with everything needed for a self-catering stay.
Our hosts were also generous (a fridge full of food on arrival, ice cream for the kids, and tomatoes most days) and very supportive (which we needed as I made a bit of a mistake on the car hire front!).
Two supermarkets are down the road, and an excellent café and ice cream parlour is just over the road.
Highly recommended (and thanks to our hosts again)!
