Short version:
The only note for somebody planning a stay here: make sure you pop by a store on the way if you are looking to cook something or have some drinks, the closest store is a 15-20 min drive. Other than that, you are in for an absolutely lovely and somehow unique experience.
Longer version:
We stayed at the farm for 2 nights, and I must say this was a great experience. We had been driving around Ireland before staying here and this place is definitely our favourite.
You have everything you need at the house, even a bit more (some breakfast stuff, fresh milk, washing machine, toiletries, etc.), so no need to worry about it. If you need some extra food or drinks, make sure you stop by a shop on the way though, the farm is a 15-20 min ride from a proper store.
The place is clean and comfortably hosts 4 people, I can imagine that more people can sleep on the couch.
The location is beautiful though - a quiet rural area with a lovely view. The farm itself is a fun place to visit, especially if you are, like us, city folks. We loved petting Rose (the farm dog), and playing with a kitten. Cows are also amazing.
The hosts, Ann and Donal, are wonderful people, very open and kind. We really enjoyed chatting with them and learning about Ireland.
Highly recommended, we even thought of staying longer than planned.
