Along with my wife and two children (one big, one small), we spent a week at Eamonn & Regina's place in Newport. It was perfectly clean, well-enough provisioned (hooray for sharp kitchen knives!), and very functional. It is neither spacious nor luxurious, nor is it trying to be, so light and comfortable in line with expectations.
Well located in terms of being close to Newport, a small town with a number of good cafes/pubs/restaurants; and Newport is well located to explore the region. Don't miss Achill Island (especially the trip around its southern coast to Dooega) or Ballycrory National Park. Both really beautiful. The exact setting of the place is plain, but it is a 5-minute walk to town and there are really lovely views over the water and sunset just 200 meters down the road. For a breath of forest air, don't miss the small hidden park in the forest above Quay Road.
All in all, a lovely place with excellent value for money, even if we did not get a chance to use our sunscreen.
