Beautiful venue, mirror chapel, with a great history. Only one small complaint - I needed to urgently go to the loo, and was told by an uninformed official in the ticket office that there were no toilets in the complex, including in the mirror chapel. I was asked to go find a restaurant, which I did. Upon my return, as I sit in the chapel, I see the sign for the WC, and several guests visiting it. Well, c'est la vie!
