5+ stars for the location. We dropped off our bags, walked out the door, and were at the start of the Diamond Hill hiking trail within 5 minutes. The entrance to the park is literally around the corner. There's a cafe, pub, and grocery store all within ~300 feet. It was a fantastic base point for Kylemore Abbey. There is plenty of parking.
Things to note: 1) to check-in, wander into the attached restaurant and look for a staff member; 2) we only had one room key, which was a bit tricky because we were a group of 3 friends who were coming/going separately; 3) we wouldn't have found this lodging if it weren't on Airbnb, so I appreciate the listing here, and even though the description refers to it as a hostel ... I was still surprised when we checked in and the room/bathroom were hostel-quality. I'd still recommend staying here for all of the reasons listed above, but it's not like other places I've stayed through Airbnb.
