I really liked Andrew. He was a great guy and took us all (in two carloads) for a lovely hike. He brought us coffee and a French press, and was very responsive via messages. He made dinner reservations for us and brought loads of wood when we asked him, was friendly, and seems like an interesting fellow. The location is really great - and it's at the end of a great hike and the Wicklow Mountains are out the backdoor. There was lots of room, and I think this place would be great for a group of adult friends who visit in the spring.
Andrew is right to warn that it does get pretty cold at night, and literally it felt colder inside than outside-We could see our breath inside. There is no hot water in the taps. You have to boil it yourself or use the butane boiler. The cabin is very dark at night. The refrigerators were unplugged (but, it was so cold we just left the food out). For hot showers you have to go through another traveler's room in another building during specific times.
