Jilba Cottage is a lovely secluded place to stay, situated at the foot of the Porongurups (quite literally, as there's a decent hill about 75m away). The surrounding gardens are beautifully kept, the view from the verandah is impressive - you can clearly see the Albany Windfarm, about 35km away - and your only background noise are birds by day, frogs by night and the wind in the trees.
Inside the cottage has everything you need to remain comfortable and especially warm during the colder periods, with some of the most comfortable bedding I've encountered in a stay away from home. A special mention must go to the provided breakfast - the fresh eggs and honey from the farm itself were fantastic! Finally, I would challenge anyone to find a place that is kept as clean as Jilba, because it was almost like staying in a display home.
Overall, if you're looking for a quiet retreat that's both not too far and not too close to towns and attractions (and I haven't even touched on how close it is to the various hiking trails in the area), I can't recommend Jilba Cottage highly enough.
