The postcode SA46 0ED will bring you to the approximate area.
The cottage is easy to find as it is the first building that you come to on the righthand side in Aberaeron on the A482 Lampeter Road as you driving towards the coast from Lampeter.
If driving from the coast direction it is the last building on the left as you drive out towards Lampeter. If you leave the 30mph area you have driven too far.
Note that the cottage is tucked down below the road level facing down the valley, so you can only see the roof from the road.
