We thoroughly enjoyed our stay at Natalie's guesthouse! The place is modern, immaculate, and cozy. The bed was so comfortable and the duvet was perfect for the late October chill. If you prefer to make your own meals, the kitchen is well-equipped and there is a small and convenient grocery store/gas station on the main road before heading up the hill to the guesthouse.
My wife lost her COVID vaccination card on our walk from Slane village (a short 15-minute walk) back to to the guesthouse on Halloween night. Natalie was so gracious and offered to overnight ship the card to us if she found it. Thankfully, my wife found it when she retraced her steps back down to the village from the guesthouse. Be careful walking at night because there are no lights or sidewalks from the main road to the guesthouse. We used the bright lights on our phones to let drivers know we were walking on the road and didn't have any problems.
If your travels in Ireland take you along the ancient and historic Boyne river valley, you should definitely stay at Natalie's place!
