I highly recommend Teach Peadar, we stayed for a week as a family of 6 (4 adults, 2 small children). The house is in a beautiful location, with views of the mountains to the back and the sea to the front. It is within a short drive to stunning beaches and tourist spots within Inishowen whilst also being in a peaceful location.
The house itself was well equipped, spotlessly clean and comfortable with everything you need for a stay. There is a stunning garden to the back which was lovely to sit in. As a host Martina is very friendly, helpful and was keen to ensure we had a lovely holiday. We will definitely be back for another stay!
