We just spent a week in Jack's Rural Retreat. We found it to be a fantastic base for exploring Kerry. It's a few minutes from Castleisland and well situated between Tralee and Killarney. It's extremely peaceful.
We happened to arrive during the hottest week of the year. Unfortunately we were unable to source a fan which wasn't great as we were traveling with our 8 month old. Thankfully Jack and his family provided us with their own which was above and beyond but thoroughly appreciated.
All in all we had a brilliant stay and wouldn't hesitate to recommend it others.
