Spent a couple of days over Easter in Dunlewy. The house worked out very well, the location is fantastic (with Mount Errigal providing a magnificant backdrop), there is loads of space, it was just as described on Airbnb and Chris, our host, was very friendly accommodating and helpful.
If you're looking for a comfortable and sapcious place to stay in the wilds of Donegal then I would definitely give this a strong recommedation
