This place looks great - its absolutely beautiful, but outside the riad is a rabbit warren of tunnels that are frankly, dirty and scary. I would not walk through there on my own day or night, so if you are a woman, don't stay at this place on your own.
The manager promised to send us our shirt back to Australia (because it had been stained at the Riad)....but the shirt didn't show up. We emailed the manager about it and she replied something like " we sent it from France but its weird that you didn't receive it, sorry about that".) We thought that was a pretty lame response and we wonder whether the onwer kept the shirt for himself.
We found the town of Marrakech difficult - the local Moroccans seemed hostile - we were told to "[--] off" by two promoters outside a restaurant in the open air markets at Jemaa al Fna because we decided not to eat there and we were almost mugged (we got away because I screamed) when walking towards a restaurant that the manager of the Riad Aya had recommended to us (ie: it wasn't "out of the way"). You will get hassled beyond belief in Marrakech. You cant walk a few steps without being hassled. I don't like writing a place off but I wouldn't recommend anyone to go there, especially not a female on her own.
We decided that we would stay in the Riad after the attempted mugging, because we couldn't stand the pollution or hostility outdoors. I had to cover my nose and mouth with a scarf when walking outdoors because of the dense pollution. I have been to China, Manila and Hong Kong and I haven't experienced pollution quite like this before.
There was no room service or food available (apart from breakfast) when we were there...which was very disappointing, because there was a menu but we were told they were too busy to serve us food...it was difficult because we didn't want to leave the Riad and brave the hostility and pollution outside, but we had to, to get food.
If you want to experience the desert, I would recommend Jordan instead.
