We stayed at Cae Du last year and liked it so much we returned this year. We stayed both times in October, and got lucky with the weather both times. We particularly love the garden - many acres of the side of a river valley to wander in, including a couple of rock pools which (some!) of us loved to swim in. It was great to be able to let our dogs just run free in the garden.
The house is well presented and comfortable, with lovely views across the valley. It is a steep walk down to the river which runs along the valley, so you do need to be reasonably agile to explore it.
