From me I offer two places. Both very different places, but similar theme.
Option 1 - Cottage in the North of the Eden Valley, well away from the main road. Fantastic view across the river towards Cross Fell, long walks in the evening bat-watching, places to sit painting the bridge, fields full of grasshoppers to catch and place under the hat (really weird feeling!). Friendly and helpful people.
Option 2 - Cottage outside Coldstream. Holy Island nearby, well worth staying over high tide, loads of bats, and even hissing Barn Owls. Friendly and helpful people. Great roads for motorbikes.
If you want to relax, why go abroad?!? So many great places in this country!
