After having a bad experience with a Riad with cats (i'm terribly allergic) in Fes, this was a huge breath of fresh air. We arrived to Jemaa el Fna at the absolute worst time for travellers (in the early evening) and were harassed all the way to the riad. However, when we walked through the door of the riad, we had an amazing experience. Despite the fact that I don't speak a world of italian and murder French, we were still able to communicate with the Manager. Throughout our stay, we had a wonderful time.
One warning, we stayed in the ground floor room (which was beautifully decorated and very clean) and when you flushed or if anyone else in the riad flushed, you got the lovely smell in the bathroom. We dealt with it by opening the window a crack and closing the bedroom door and that seemed to work.
If I ever get back to Marrakech, I will definitely stay here.
