Near the junction where you can turn right for Whitehaven or left for Millom, do neither. Instead, just before this you'll see a small lane on the left which leads to Hallthwaites (there's a church where the road divides for Whitehaven and MIllom)
Go down to the bottom of the hill and you'll see two cream coloured cottages (semi detached) with light green window surrounds on the Right Hand Side. One is Rose Cottage, the other is Little Rose Cottage
The parking space is right outside of the door
The postcode for Little Rose Cottage is LA18 5HP. Please follow the above directions to find the cottage.
