We stayed here for a week in July- family of 5 (2 adults, 3 kids 16,14, 8), plus one visitor for a few nights. Plenty of room for all. The cottage is even more beautiful than what you see in the photos. Everything you need and beyond. Sometimes I would just sit by the fire and look around at how beautiful the home is. Angela's sister Gertrude made sure that we were happily checked in and showed us around the place. The property is gorgeous and has lots of room for kids to run and play. The beach!! A short walk down a relatively quiet road. It's all sand and shallow swimming -perfect for kids who just want to explore the little pools in the rocks and play in the shallows, and you can go for a nice swim too if you want to venture out further. We saw lots of kids surfing. The location on the Inishowen Peninsula is remote and quiet, but not too far from towns where you can get some food and wander. Try Nancy's Barn for food - reservation needed. We only left to go to the Giant's Causeway (really fun to take the ferry), otherwise we were occupied by all the stunning places to see on the peninsula itself. Highlights were Malin Head walk and a "raised beach" nearby that is all round rocks and nice swimming, the Wild Alpaca way, Five Finger Strand (don't swim there!, but go for the dunes and to watch the wild sea), and Inishowen Head Loop.
My kids want me to mention that there is a spinning chair on the second floor that they loved. I'd also put in a good word for the bathtub!
