In reply to M1EYP:
We used this site http://www.unique-cottages.co.uk last year and I have booked two cottages again this year from them for a two week break starting the 18th August; 1st week in Dumfries, the second week near Selkirk.
We stayed as most of you know in Wanlockhead (Cottage Ref: BC9) last year, miles from the shops but a lovely area; this cottage was across the road from Green Hill SS-123, at the top of the village is Green Lowther SS-056; plus SS-131 Hods Hill is on route off the motorway towards Wanlockhead. Then moved on to Dunkeld (Cottage ref BP9) was the second week the house was down a long drive; the house could have been better; had a funny smell in main bathroom and the kitchen, well my pantry is bigger, but the views; including the deer, squirrels etc outside the door and the location made up for what it lacked. We looked directly at Deuchary Hill CS-108, lots of sota summits around here including CS-065 Ben Vrackie, would have loved to climb this.
In years gone by we have stayed in Lochgoilhead, a long, single track road down from ‘Rest and be thankful’ lots of sota summits around there, shops well again a long drive as Dudoon is the nearest town; the kids loved this one as we had the use of a boat and we watched seals in the loch. http://www.Hoseasons.co.uk have a park in Lochgoilhead.
we stayed two years ago in Kirkcowan just outside Newton Stewart at this cottage ref 18818 on http://www.cottages4you.co.uk, great cottage, joined to owners cottage, they were very friendly!, saw lots of red squirrels here.
I would also recommended looking at http://www.undiscoveredscotland.co.uk lots of info about the villages etc.
Hope these help, but know what you mean, my problem now is what summits do we do this year, so many SS ones.
