I have experience with + 20 escape rooms and this one would be definietly the more difficult type - but not in solving the clues - in spotting things and following correct leads. The room is offering LOT of locks with keys. There are LOTs of useless things you find that are only there as a distraction. Important things are hidden in strange places, you cannot leave any stone unturned. Somehow its missing important clues to at least have an idea where to look. The riddles are not very difficult. Not my favourite type of room, but I have to admit - very beautiful.
