I was given directions to these toilets by a lady in a cafe in the Louvre museum as it was the nearest but when I got there I was astonished to find the price displayed as 1.50 Euros to use them and a woman cleaning them who had seemingly got a good business going with cash machines and every facility to charge the customer. I would never pay that price just to use a toilet so left to go back to the hotel.
