Sinead's place, Hidden Hills is amazing. It is off the beaten path and so peaceful and beautiful, yet still close to town, only 10 minutes. Sinead is a great host. We had a bit of difficulty finding the place via MAPS. Because we were coming from the North, it routed us a very wrong (please NOTE: do not use a Map app, if coming from the north, UNTIL you are in Waterville, then it will work correctly), but Sinead was prompt in responding and helping to get us to the place.
It was very comfortable and cozy for 4 of us. It has all the basics you might need and the beds were very comfortable. This is a working sheep farm and they offer a sheep herding demonstration for a minimal fee, which is so interesting and educational. If you are going to be in the Waterville area I highly recommend this place and town. It is also close to many places to see in Ireland.
