We had a fantastic stay at Kilian's property in Mornington. The cottage was actually much larger than it looked and had plenty of room for three of us. It is on a small road but is not noisy.
Communication with Kilian was great, very flexible about our arrival time [delayed flights] and he quickly showed us what was what. The cottage was bright, clean and comfortable. It was really well equipped, far better than some cottages I have stayed in , with some thoughtful extras like shampoo, books and maps/guides and leaflets, basic cooking/food items and a welcome loaf of [lovely] bread and some bacon. Nice spotless bathroom, comfortable beds and two rooms for lounging in. There's a nice outdoor area too but as we were out all day we didn't really use this other than early evening.
Good parking area and a great location for the areas of Meath we wanted to explore for family history and local history.
Kilian recommended The Lime Kiln in Julianstown and the food was good, great friendly service too.
There are a few passage tombs in the area, Newgrange and Knowth being the most famous. We opted for Four Knocks as it was on land our distant family once owned and it was delightful, we were the only people visiting and it had a really special quality [see trip advisor for getting hold of the key].
The nearby petrol station on the way to Bettystown has a food shop where you can get most stuff you'll need.
