Coming from Australia I've never seen anything like this in my life and I thought it was great! It was surprisingly warm inside and I don't know if I'd want to stay the night, but was cool for a walk around.
It only takes an hour tops, so if you catch a taxi see if they will come back in an hour to To get you. did not like the cafe; we had to stand at the counter for 15 mins until the came from behind the curtain to just serve us. We were the only ones in the entire place as well so it was frustrating as it was not busy! The decor in the cafe was nice though.
So loved the castle... Give the cafe a miss if you can.
