The castle is very nice -- clean, tidy, charming space, and getting to it through the "maze" is a mini adventure that the kids loved. Quite convenient to market, bakery, pharmacy, and main road. It's a bit of a hike from the parking, so pack light! The bathrooms (3 of them!) are clean and totally useable, but be aware that they are combo units -- toilet, shower, and vanity all in one space, with a drain in the middle. This is very common in many places outside the United States and is just part of the adventure.
Overall, a great place. Recommended.
