The Valley House is a really nice location at Achill Island, especially if you're doing a backpacking trip or looking for a nice hostel for day trips.
We stayed here during our family vacation with our 1-year-old son. For us, it wasn't a fitting place, because of emergency lights and thin walls that kept our son from sleeping.
All in all, we think the Valley House is a great place, but it wasn't the right place for us in our situation.
