WOW. If you are thinking about doing this, DO IT. Tell your mom to do it, your best friend, your boyfriend, your grandma, random hostel friends in Dublin, literally tell everyone.
This stay is 100% worth what you spend on it. I was given a great tour of the grounds, with a great background story of how it came to be, and what their plans for the property are. The room is amazing, ~*heated floors*~, and I had the best night of sleep this trip here. If you’re nice enough, you might also be let to walk on the ROOF of the tower. 😍
