Stayed in the Ark floating house with my wife and 2 kids recently, the house was excellent, all the facilities and space of a house but located like a boat, right on the waterside with unobstructed views across the river. The floating house has a rooftop terrace which we didn't get to use due to the weather but I can imagine sitting out there on a warm evening watching the sun go down. The setting is so picturesque with plenty of wildlife about. Good location too, not far from one of the best forest parks in the country; Lough Key, but near enough the larger town of Carrick on Shannon. Paddy was a great host, friendly and accommodating. We're booked in to return soon, and will likely keep returning.
