Eileen's cottage was lovely and cosy and we had a really good time.
Lettermacaward was such a nice village; Elliots was great fun on Friday night, and you were close to the beach and easily accessible to much of South Donegal.
We did find the cottage a bit cold and couldn't get the heating to work very well, which loses a star. There is a wood burning stove, so if you are visiting in the colder months I would recommend buying some wood. Eileen did provide a fire log, but by itself it didn't do much.
Also don't blindly follow google's directions to get to Lettermacaward. We were taken on an unpaved single track road over a hill, only to find a newly tarmac's main road on the other side!
I would definitely recommend Eileen's place, but be sure to bring slippers and house coats if you're coming in winter.
